The Release Info Tekla Structures 2020 includes the following topics:


Tekla Structures 2020 video's

Tekla Structures 2020 provides many new options, improvements and fixes. These are all explained in this Release Info. Besides, some videos are available in which these functionalities are explained.

You can check the following videos (per segment):

Renewed logos in Tekla Structures 2020

Trimble has started to refresh logos, product icons, etc. for all brands within the Construction sector in 2020 to make the brand image consistent and clearer, along with the other brands they supply.

These changes have also been made in Tekla Structures 2020 so that you will find the renewed logo in many places, for example in drawings:

It is therefore possible that sometimes the old logo is still displayed in Tekla Structures 2020.

Use separate ts folder per Tekla Structures version

For each Tekla Structures version, you have a ts folder where you can save custom settings so that they are available in all Tekla Structures models. The default location for the ts folder in Tekla Structures 2020 is:

This location is defined by the advanced option XS_FIRM in the Advanced optionssettings used to customize Tekla Structures for specific companies, standards, users, or user groups

In Tekla Structures, advanced options are settings that are used, for example, in a specific project or geographical area, or by a specific company.

In Tekla Structures, advanced options usually begin with the initials XS and are followed by the name of the function, for example XS_BACKGROUND_COLOR.

(via File > Settings > Advanced options).

When multiple licenses are in use in one company, it is often desirable that everyone points to the same ts folder so that everyone uses the same profile catalogcatalog that displays profiles and information on the profiles

In addition to the available profiles in the respective Tekla Structures environment, the user can add fixed or parametric user-defined profiles to the profile catalog. It is also possible to import profiles to the profile catalog.

, drawing settingssettings that control what the drawing looks like and what it includes

Drawing settings can be defined in the modeling mode when creating a drawing, and they can be modified in the drawing mode.

The range of the objects and elements that drawing settings affect may vary.

, templates, etc. In those cases, it is useful to have the ts folder located on a server.
This obviously promotes uniformity within the company. The advantage is that you only have to maintain one ts folder and after a change everyone is "up to date" immediately.

When working with different Tekla Structures versions, you always create a separate ts folder on the server for each Tekla Structures version. You do this because settings can differ per Tekla Structures version, for example due to new functionalities or changed user-defined attributes.

It is therefore preferable not to use settings of, for example, Tekla Structures 2019i in Tekla Structures 2020! Consider, for example, the settings (files) for the layout in drawings, see also chapter Drawings> Adjust drawing layouts with the improved Layout editortool that enables editing the table layout directly on a drawing

In the layout editor, it is possible select which tables are included in the table layout and where they are placed. The table scale, and rotation and overlapping with drawing views can be adjusted.

In addition, since Tekla Structures 2019i, you already had the option to use subfolders in the ts folder and save your own settings in these subfolders in order to organize them in a structured way and make them easier to manage.

New user interface for rebar catalog

Tekla Structures 2020 introduces a new user interface for the rebar cataloguser interface for displaying or modifying information in categorized lists

For example, profile catalog and shape catalog are catalogs.

(via File > Catalogs > Rebar catalogcatalog that displays reinforcing bar types with a predefined bending radius and hook dimensions

). The rebar catalog contains definitions for reinforcing bars and strands. You can add, modify and delete rebars in the catalog:

To edit reinforcing bars, you used the file rebar_database.inp file in earlier Tekla Structures versions. In Tekla Structures 2020, you can make changes in the new rebar catalog, which automatically updates the file rebar_database.inp
The new rebar catalog is also being used when you select rebars in property dialog boxes:

Updating model templates

In case you have created model templates in earlier Tekla Structures versions, you must update the templates to use them hassle-free in Tekla Structures 2020.
Click here for the general step plan.

Copy customized ribbon and shortcuts to Tekla Structures 2020

You can copy your customized ribbon and shortcuts (after installing Tekla Structures 2020) from an older Tekla Structures version to Tekla Structures 2020.
Copy the ribbon
You can copy your customized ribbon from an older Tekla Structures version to Tekla Structures 2020.
If you copy your customized ribbon, new available (in Tekla Structures 2020) command buttons will be missing, for example the new command Rebar in the Drawing Editor for dimensioning rebar groups:

You can also first compare the "old" ribbon with the new "standard" ribbon in Tekla Structures 2020 via File> Settings> Ribbon> Compare in both Model and Drawing Editor:

You will see the differences between your customized ribbon and the "default" Tekla Structures 2020 ribbon, for example the new Rebar command:

You can now choose to add the missing command buttons or to use the new "standard" ribbon.

You can do next to copy your customized ribbon:

1. In the Windows Explorer, go to the folder (depends on the Tekla Structures-version)
C:\Users\<user>\AppData\Local\Trimble\TeklaStructures\<older version>\UI\Ribbons\                                            
or the folder
C:\Users\<user>\AppData\Local\Trimble\Tekla Structures\<older version>\UI\Ribbons\
2. The *.xml file: albl_up_<license>--main_menu.xml contains the customized ribbon.
3. Copy this *.xml file to the folder C:\Users\<user>\AppData\Local\Trimble\Tekla Structures\2020.0\UI\Ribbons.
Click here for more detailed information about copying the ribbon.

Copy shortcuts

To copy shortcuts from an earlier Tekla Structures version to Tekla Structures 2020:
1. In an earlier Tekla Structures version, go to File > Settings > Keyboard shortcuts.
2. Click on the button Export, save the *.xml file on the desired location with the desired name.
3. In Tekla Structures 2020, go to File > Settings > Keyboard shortcuts.
4. Click on the button Import, select the *.xml file and click on the button Open, the shortcuts are now imported.
You can copy the exported *.xml file to any computer and next import the file in Tekla Structures 2020.

New report castunit_sub-assemblylist and template Castunit_sub-assembly available

In Tekla Structures 2020 the new content typedetermination of which template attributes can be used in the template object value fields for a template component row

Content types are mainly based on object types.

HIERARCHIC_CAST_UNIT is available for concrete subassemblies. Because of this, Tekla Structures now includes the new report castunit_sub-assemblylist and the template Castunit_sub-assemblyassembly in a nested assembly that is subordinate to a parent assembly


The report and the template are intended for concrete subassemblies, for example a sandwich panel including a concrete subassembly:

... or a corbelconcrete part representing a structure that projects from the face of a concrete part and that serves as a support for an overhanging part and connects the parts

that has been added as a subassembly to a concrete column (because the console will be poured later):

New profiles added

Tekla has added two new parametric profiles, so Tekla Structures 2020 now includes the two following new profiles:



Update files and extensions from previous Tekla Structures versions

As a Tekla Structures user, you can use a checklist (installation log) that you may have created in a previous Tekla Structures version. Here you can document and save all your changes regarding Tekla Structures. After installing Tekla Structures 2020, you can quickly see what needs to be adjusted or checked so that you can get started with Tekla Structures 2020 quickly.
In addition, you can use the wizard Migration in Tekla Structures to copy various personal settings and extensions from a previous Tekla Structures version to Tekla Structures 2020. The wizard Migration opens automatically when you start Tekla Structures 2020 for the first time:

If you want to copy the settings later, you can start the wizard Migration manually by double-clicking the file MigrationWizard.exe in the folder ..\Tekla Structures\2020.0\nt\bin\applications\Tekla\Migrations or by searching in Tekla Structures for migration in the Quick Launchtool that is used for quickly finding commands, dialog boxes, and other functions in Tekla Structures

For example, local content in Tekla Warehouse can be found using quick launch.

featurepart of Tekla Structures functionality that is maintained and owned by Trimble Solutions and that is included in the Tekla Structures installation


You can also use the Tekla Structures Extension Package (TSEP) builder and test runner (TeklaExtensionPackage.Builder.exe in the folder ..:/TeklaStructures/2020.0/nt/bin) for installing and/or deleting one or more extensions:

To install an extension in a selected Tekla Structures version:

... or delete several installed extensions very fast:

Using predefined rules in the Template Editor

You can use several predefined rules (as a basis) in rows in the Template Editortool in Tekla Structures that is used for creating and modifying templates to be used in drawings and reports


Open the Template Editor (via File > Editors > Template Editor) in Tekla Structures and create or open an existing template/report and double-click on a row. The following dialog box appears:

Next click the button Advanced, you can now select predefined rules in the drop-down list:

When you select a line in the drop-down list, the content is shown immediately:

You can save your predefined rules (with adapted conditions) as follows:

Modify a condition and click button Store..., the following dialog box appears:

Enter the name for the predefined rule and click OK, the rule is now stored and visible in the drop-down list immediately:

All modifications are stored in the file rules.txt in the folder:


Restart Tekla Structures to be able to use the modifications in all Tekla Structures models.


New point cloud settings and other improvements

You have the option to add point clouds in your Tekla Structures model since several Tekla Structures versions.
In Tekla Structures 2020, the side pane command Point clouds has been completely updated. The new point cloudgroup of measured points that are imported to Tekla Structures as one unit

Point clouds can be placed by the model origin or by a defined base point.

functionalities are available when you have added a point cloud and when DirectX renderingprocess of making the model object faces visible

The rendered model object faces can be transparent or non-transparent

(via File> Settings> DirectX rendering) is enabled:

You can now rotate and scale point clouds and adjust its location. To be able to change the values, you need to select the point cloud in the side pane.
You can use EDL (Eye-dome lighting) effect to improve the depth perception of the point cloud. Drag the sliders to increase or decrease the outline thickness and strength of the point cloud. You can deactivate the EDL effect by clicking the EDL button:

You can also check clashes and deviations: Detect points that are inside or within a distance from the selected parts and selected reference models objects based on adjustable settings. Set the visualization setting to Clashes: ​

The interference between Tekla Structures objects and point clouds are visible in the model viewview that is represented in the modeling mode

Model view is available also in the drawing mode and it is represented in its own window.

using a color code where you can define the tolerance values yourself.

Export grid to IFC by default

Tekla Structures includes the option to export your Tekla Structures model to IFCfile format commonly used in BIM that facilitates software interoperability

IFC is an open specification developed by the IAI (International Alliance for Interoperability).

Model can be exported into an IFC file.

by default via File> Export> IFC, the Export to IFC dialog box appears:

On the Parameters and Advanced tabs, you can define the details for the Tekla Structures model to be exported to an IFC file.
In Tekla Structures 2020, on the Advanced tab, the check box Gridmodeling aid that represents a three-dimensional complex of intersecting grid planes or intersecting grid planes and curved grid surfaces

The grid is defined by coordinates in 3D space. It is shown two-dimensionally on the view plane by dash-and-dot lines. A grid can be rectangular or radial.

It is possible to have more than one grid in a model. For example, a large-scale grid for the entire structure, and smaller grids for some detailed sections.

It is also possible to show grids and grid line labels in drawings, and to modify how they are shown in the drawings.

is now selected by default so that grids in the Tekla Structures model are included in the export to IFC by default:


Trimble Connect Business-license for Tekla Structures users

At the end of 2019, Trimble announced that from 2020 it is not possible anymore to download Tekla BIMsight (as project collaboration software) and that support and developments will no longer take place. The main reason for the end of Tekla BIMsight is Trimble Connect(1) application for information sharing and collaboration for construction projects that is based on the Trimble Connect platform

(1) Reference models are used in Trimble Connect application instead of using import and export.

(1) Trimble Connect application includes web, desktop and mobile clients, and the Sync tool, for example.

(2) Trimble’s platform for microservices in the cloud

(2) Trimble Connect platform’s microservices include services for uploading, storing, processing, and managing or consuming data. These services are meant to provide common solutions required by multiple applications.


Trimble Connect enables collaboration for engineering and construction projects, local and via cloud service, and is accessible via Desktop, Mobile or Web. Trimble Connect allows you to view, share, and access project information from anywhere at any time. You can combine 2D and 3D file formats, such as IFC, STEP, DWG and SKP. You can even add annotations in Trimble Connect.
It is no problem if you want to continue using Tekla BIMsight. You can still export your Tekla Structures model to an IFC file and open it in Tekla BIMsight. However, you can also choose to open your current Tekla BIMsight projects in Trimble Connect.
As of this year, you will receive a free Trimble Connect Business license with your Tekla Structures maintenance license. You can use this license by yourself or assign it to a colleague within your company. The free Trimble Connect Business version includes the following features:

- The extension Linking Documents to Trimble Connect, available in Tekla Warehouse.
- Defining property sets (such as production status, transport status) and the object browsertool in Organizer used to inquire, view, and report model information based on selected model objects

Collaboration between Tekla Structures and Trimble Connect

Tekla Structures includes many improvements regarding to the collaboration between Tekla Structures models and Trimble Connect-projects.
1. Link Trimble Connect project in Tekla Structures 2020
You can now link your Tekla Structures model to a Trimble Connect project either right away while you are creating a new model by selecting the Start Trimble Connect collaboration check box on the start screen:

To link an open model to a Trimble Connect project, on the File menu, select Start collaboration.

In both cases, the Trimble Connect - Select project dialog box opens. Here, you can select if you want to link your model to a new Trimble Connect project or an existing one:

2. New buttons on the tab Trimble Connect in the ribbon

The tab Trimble Connect includes many new buttons that make it quicker and easier for the collaboration between Tekla Structures and Trimble Connect:

Click here for detailed information about the new buttons in the tab Trimble Connect in the ribbon.

3. New Connect overlay models
You can now use overlay models in Tekla Structures 2020.
An overlay model is a lightweight reference modelmodel which the designer can use as an aid when building another model

A reference model is created in Tekla Structures or in other software and can be inserted to Tekla Structures. The reference model appears together with the model but it is not modified by Tekla Structures. The user can snap to reference model points.

For example, an architectural model, a plant design model, or a heating, ventilating, and air-conditioning (HVAC) model can be a reference model.

that is stored in a Trimble Connect project. Overlay models show model objects, parts, rebars, bolts, and assemblies on top of Tekla Structures models. However, pours and pour units are not shown. You can attach overlay models to your Tekla Structures model, view the attached overlay models in a clear tree structure, and manage overlay models in several ways.
To start managing overlay models:

► Click Models on the tab Trimble Connect and ensure that the Overlay models tab is open:

Here, you can:
- Hide or show overlay models by clicking the and icons.
- Adjust the scale and position of overlay models in the Properties section.

Export Tekla Structures models to Trimble Connect

To export Tekla Structures models to Trimble Connect, you export your Tekla Structures model to IFC and next open it in Trimble Connect:

NOTE: You also have the command in Tekla Structures to export directly to Trimble Connect via File > Export > Trimble Connect. However, you do not use this command; you follow the step-by-step plan below.

The following Trimble Connect versions are available in Tekla Structures (you possibly need to log in with your Trimble Identityuser account to sign in to both Trimble and Tekla products and online services

For a Tekla Structures user, Trimble Identity is a single sign-on account which enables the user’s online identity management. Trimble Identity is needed, for example, for Tekla Warehouse, Tekla User Assistance, and Tekla Campus.


- Trimble Connect 3D Viewer , this is the online version.

- Trimble Connect Desktop , click here for the download. Click here for an instruction video about Trimble Connect Desktop.

Step plan

1. Open a Tekla Structures-model.

2. Before exporting the Tekla Structures model, check whether the parts you want to export, include the correct IFC-entity and IFC-export type.

3. If needed, create a base pointpoint in a model that is used to define a starting point in surveying and that is used as an anchor point in coordinate and height transformations

A Tekla Structures project can have several base points but only one of them can be the project base point.

Base points allow the use of another coordinate system needed for interoperability and collaboration. Base points can also be used in drawings, and in reports and templates. Model origin is the default base point in Tekla Structures.

Base points are also called control points.

in your model for the IFC file, click here for more detailed information.

4. Select the entire model or select the model objects that you want to export.

5. Click File > Export > IFC, dialog box Export to IFC appears:

6. If needed, you can define property set configuration files (field Additional property sets) besides the predefined property set configuration files to define which user-defined attributes are exported as property sets into IFC models. Click here for more detailed information.

7. Click Export, the IFC file is created and stored in the model folderfolder that is used for storing files associated with a model

Tekla Structures stores all files associated with a model in a folder it creates with the same name as the model database (.db1).

In multi-user mode all users access the same model folder.

by default.

8. Open Trimble Connect, if needed log in with your Trimble Identity.

9. Link the Tekla Structures model to a Trimble Connect-project:


10. Next add the IFC file to the project by dragging it from the Windows Explorer into Trimble Connect:

11. Double-click on the button View to open the IFC file:

Click here for detailed information about Trimble Connect.

Click here for an instruction video about the collaboration between Tekla Structures and Trimble Connect.
Link documents from the Tekla Structures model to a Trimble Connect project

In Tekla Structures you can use the extension Linking Documents to Trimble Connect to links documents to a Trimble Connect project:

The extension is available in Tekla Warehouse and links from model objects in the Tekla Structures model single part-, assembly-, cast unit- and GA drawings, NC files and IFC files to the corresponding objects in the Trimble Connect project.

NOTE: The extension Linking Documents to Trimble Connect only works if you export IFC files from Tekla Structures and insert them into Trimble Connect, not if you exported directly from Tekla Structures to Trimble Connect (* .tekla file) via File > Export > Trimble Connect.

In addition, for the Linking Documents to Trimble Connect extension to work correctly, the following also applies:
When you create drawings in Tekla Structures, a snapshot of the drawings is automatically created. Every time you edit a drawing and save it, a new snapshot of the drawing is automatically saved. This applies to all drawing types. Two variables affect the creation of drawing snapshots:
XS_DRAWING_CREATE_SNAPSHOT_ON_DRAWING_CREATION: This advanced option is set to TRUE by default to create a snapshot of a drawing at the same time that you create the drawing.
XS_DRAWING_SNAPSHOT_CREATION: This advanced option is set to TRUE by default so that snapshots are created automatically when you save a drawing.

If you switch off creating snapshots in Tekla Structures, a message appears asking you to set the advanced options to be able to export the drawings to Trimble Connect.

Click here for detailed information about the usage of the extension Linking Documents to Trimble Connect.


Modeling curved shapes: improvements in lofted plates and lofted slabs

Tekla Structures 2019i introduced modeling new steel lofted plates and concrete lofted slabs by using construction objects:
Two construction lines A construction line and
a construction arc
Two construction arc Two construction circles A construction object
and a point

In Tekla Structures 2020, the creation of lofted plates and lofted slabs has been further enhanced and you can now model even more complex curved shapes by using polycurve construction objects:

Before creating lofted plates or lofted slabs, you need to have modeled polycurve construction objects. Tekla Structures creates the shape of the lofted part according to the geometry of the polycurve construction objects.

Additionally, you can now unfold lofted plates in single-part drawings:

Click here for more detailed information about modeling lofted plates and lofted slabs.

Part representation in model views

In Tekla Structures 2020, the DirectX rendered model views (via File > Settings > DirectX-rendering) have been improved.
Part edge lines are shown as dashed lines in transparent model views
In DirectX rendered model views, the part edge lines that are hidden behind another part are now shown as dashed lines in all transparent views whose rendering option is one of the following:
Part representation Shortcut combination
Parts wireframe Ctrl + 1
Parts shaded wireframe Ctrl + 2
Parts greyscale Ctrl + 3
Show only selected parts Ctrl + 5


Component part representation Shortcut combination
Components wireframe Shift + 1
Components shaded wireframe Shift + 2
Components greyscale Shift + 3
Show only selected components Shift + 5

(Tekla Structures rendering can use either DirectX or OpenGL technology. To improve the rendering quality, you can set Tekla Structures to use the DirectX rendering engine instead of the default OpenGL-based rendering engine. The DirectX rendering adds a subtle shading effect to Tekla Structures objects, making the 3D visualizations clearer and more defined).

If you want to show the part hidden lines in DirectX rendered views, set the advanced option XS_USE_DASHED_HIDDEN_LINES to TRUE.

The advanced option is set to FALSE not to show the part hidden lines:

Model objects have thicker edge lines

In DirectX rendered model views, all model objects, except reinforcing bars, have thicker edge lines than previously. The edge lines for reinforcing bars remain the same as they have previously been. This change improves the previously experienced blurriness of edge lines.

Anti-aliasing in DirectX-rendered views

Anti-aliasing is now on by default in DirectX rendered views. The advanced option XS_USE_ANTI_ALIASING_IN_DX is set to TRUE by default. Previously, the default value was FALSE.

Click here for more information about the advanced option XS_USE_ANTI_ALIASING_IN_DX.

Click here for more information about changing the rendering mode.

Sketch Solver package in Tekla Structures

Tekla Structures includes the Sketch Editortool that is used for creating and editing parametric user-defined profiles

(via menu File > Catalogs > Define profiles > Define cross sectiongeometrical form of a part sectioned perpendicular to its axis

in sketch editor
) to define parametric profiles.

The following message appears when you start the Sketch Editor in Tekla Structures 2020 (and also in Tekla Structures 2019i):

The message tells you to install the so-called Sketch Solver package (this is an external library as a separate extension) to be able to keep defining or editing parametric profiles. The package is available in Tekla Warehouse.

When you edit sketched profiles in your Tekla Structures model or when you define new profiles, Tekla Structures checks whether the package is installed. If not, the message appears. After installing the extension, it all works in the same way as in earlier Tekla Structures versions.

When you define new sketched profiles in your Tekla Structures model, the file pgdb.bin is saved in the model folder.

Diagnose and list solid errors

The solid errors found in the currently open model are now shown in the report that opens when you use the Diagnose & repair > Diagnose model command on the File menu:

When you press and hold the Z key on your keyboard while selecting a line in the list, Tekla Structures automatically zooms in on the corresponding solid error in the active model view.

You can now solve the solid error in the model:

Improved representation for welded profiles in model views

Since Tekla Structures 2018i the representationthe way that the information included in a model is represented visually

for welded plates in model views has been improved: welded plates color light blue, loose plates don't:

Since Tekla Structures 2019, also the representation for welded RHS profiles has been improved:

and since Tekla Structures 2019i also the representation for welded L profiles has been improved:

In Tekla Structures 2020 the representation for welded U profiles has been improved:

Because of these modifications, the setting standard looks as follows:

The object groupmodel objects whose settings match the settings that the user has defined for a certain purpose

In Tekla Structures, an object group is defined by rules and conditions, for example, to control the transparency and coloring of model objects in the views. Object groups can also be used in filtering tools, for example in selection filter, to select all objects that match certain properties.

welded U looks as follows:

so that welded U-profiles (1) with the name that is equal to, for example STRINGER, do not have this representation:

Also the setting only steel now includes these object groups (1) for the representation of welded parts:

In addition, in the setting only steel is defined that parts that have the material quality cast in place, precast and timber, are invisible (2) so that only the steel is displayed.

For representing bolts in Tekla Structures 2020, the setting bolts color is added:

In addition to the object groups for the welded parts (1), the setting bolts color includes a definition for bolts with a diameter smaller than 16 mm shown in yellow and a definition for bolts with a diameter larger than 16 mm are shown in magenta (2). Bolts with a diameter equal to 16 mm are represented in the default (brown) color:

Also the settings length assembly and length part are added:

The settings define the length of assemblies and parts: assemblies/parts that are longer than 24 meters are shown in red. The other model objects are (temporarily) hidden.

If desired, you can of course customize the model view settings to your needs.

Show and modify drawing views in the model

You can show the drawing views of the selected drawings in any of the open model views to get a clearer understanding of exactly where a drawing viewview that includes selected model objects or an area in the model, that is represented in a drawing

A drawing view is a container for model and drawing objects.

A drawing can include several drawing views, which usually are two-dimensional views, plane views, to the model.

Examples of drawing views in Tekla Structures include main views, section views, single-part views, and 3D views.

is located in the 3D model, the view direction, and the 3D extents of that view.
Show the drawing views in model views

1. In the modeling modemode that is used for creating and analyzing a model, and initiating the creation of a drawing and a report

Custom component editor and sketch editor can be accessed in modeling mode.

, go to the tab Drawings & reports, open the Document managertool that is used for listing and managing drawings and other types of documents

With the document manager the user can, for example, reorganize, update, freeze, lock, and delete drawings.

The user can also organize file documents, such as PDF, NC, and DWG files, and drawings, in document categories, and search documents and open drawings.

Document manager is replacing drawing list from the version 2018i onwards.

and select one or more drawings in the document list.
2. Next click the Show drawing views in the model button in the top-right corner of the Document manager window. When this button is activated, it changes color:

The views in the selected drawings are now displayed in the model. You can then use direct modificationfunction that activates the mode where the model objects can be modified by using handles

Direct modification enables additional handles and modification options.

to work with the view extents and view planeplane in a space that defines the view

In Tekla Structures, the grids are projected onto the view plane and the grid lines can be visible on it.

View depth is defined starting from the view plane.

of every view that is contained within each selected drawing in the currently open model views.

When Show drawing views in the model is active, any changes to the selection of drawings will cause the Show drawing views in the model command to be automatically re-run. This way you can easily walk through a list of drawings, selecting one drawing at a time, and see the views for that drawing in the model:


Labels show the name of each drawing view in the model when you move the mouse pointer over an unselected view edge or when a view is selected.

Next you can make all kinds of changes in the model view of interest to automatically make the changes in the drawing view, for example the rotation of a 3D viewview that displays objects three-dimensionally

3D view is one of the default views.

System components

Modeling steps

Tekla Structures includes several system components for modeling stairs including steps, for example system componentcomponent that is included in a Tekla Structures configuration and whose component objects and composition the user can modify within the limits of the component properties

Stairs (71). Previously, in this system component, a step catalog could be used for modeling steps:

This step catalog includes many common step profiles of suppliers by default.

However, it is of course possible that changes take place in the steps, for example changes in the shape or the dimensions, or steps that are no longer available, etc. In order to provide Tekla Structures users with a current step catalog, suppliers more often make their products also available on Tekla Warehouseservice for collaboration and for storing and sharing Tekla Structures content

In Tekla Warehouse the content items are stored in collections. Tekla Warehouse includes the Tekla Warehouse Service and the Tekla Warehouse web site.

Tekla Warehouse is one of the Tekla Online services.


As a Tekla Structures user, you may have been using this steps catalog for years, knowing that the types of steps you use exist and that these types of steps are available. In that case it is of course no problem to use and continue using this catalog.

The step catalog is not available in Tekla Structures 2020 by default anymore, you can do next to be able to use the step catalog again:

1. Close Tekla Structures 2020.
2. Open the Windows Explorer and go to the folder C:\TeklaStructures\2020.0\applications\steel1
3. Delete the file ts_page_10_construsofteuropean.inp
4. Select the file ts_page_10_construsofteuropean - kopie.inp and rename the file to ts_page_10_construsofteuropean.inp.

5. Start Tekla Structures2020, the step catalog is available again.
You possibly exchange Tekla Structures models in which you or other Tekla Structures users have used steps from the steps catalog. If you or the recipient of your model did not have this step database, the model would not be complete.

However, in order to be more flexible, Tekla Structures includes custom componentcomponent that the user creates and uses for creating model objects whose composition the user can modify as a group

step for many years that allows you to model steps manually or use them in system components:

Custom component step is available in Tekla Structures by default and has the great advantage that you can save all desired types of steps. Because of that, you are no longer dependent on changes in the assortment of suppliers.

The corresponding stair-steplist has been renamed to step list. Custom component step has been adjusted so that now only the name of the supplier is shown in the list:

In earlier Tekla Structures versions also the width of the steps was represented.

New formwork placing tools for walls and slabs available

Tekla Structures 2020 includes new formwork placing tools: Formwork placing tools - Walls and Formwork placing tools - Slabs. Previously, these tools have been available in Tekla Warehouse.

The formwork placing tools enable the efficient modeling of different wallplate that represents a structure such as a wall or roof panel

In Tekla Structures, a panel is created by picking two or more points.

In cast-in-place concrete the term wall refers to a concept similar to panel.

panel and slabplate that represents a concrete structure

In Tekla Structures, a slab is created by picking three or more points.

Slab may be part of a floor, for example.

panel formwork systems.

The formwork placing tools are available in the All, Cast-in-place and Contractor roles. The tools Wall and Slab are placed on the Formwork tab in the ribbon:

and the individual sub-components included in the tools are available in the Applications and components catalog:

Online Help files available for Construsoft system components

System component Footplate (1029), Bolts between points (m093) and Wooden purlin (1) from Construsoft now include an (online) Help file:

The Help files are located in the Tekla User Assistanceonline help and self-support service for Tekla Structures

Tekla User Assistance includes instructions, support articles, and instructional videos, and it offers a possibility for feedback.

Tekla User Assistance is one of the Tekla Online services.

and therefore online available. The main advantage of this is that if the system components have new functionalities, the Help files can be modified (updated) very quickly and are therefore immediately up to date (because they are online).

More and more Construsoft system component Help files will become available online in the future.

Wood wall (57)

System component Wood wall (57) now includes several improvements:

You can now set the zone of H-frames of the opening and you can control the zone. In addition, you can now apply different starting positions on both sides of the element, whereby the position of the studbolt element that represents a metal rod or pin that is used to transfer loads

Studs and other bolt elements are listed in the bolt catalog.

A stud can be secured with two or more nuts and have threading at both ends, or it can be welded to steel parts, for example.

A stud is part of the bolt assembly.

determines the next seam for the plate(1) part that represents a flat structure

(1) In some contexts, for example in analysis, the term plate object may be used to refer to plates.

(2) plate that represents a steel structure

(2) Plate is mainly used as a connection piece or as a floor plate.


Wooden roof (63)

System component Wooden roof (63) now includes the following improvement:

If you now use the default set names in system component Wooden roof (63) for cladding and for rafters, the new settings for the dimensions will work for all zones.
In addition, the names of negative volumes have now been improved for correct export to BVX files.

Click here for guidelines (in English) that apply for detailing wooden parts for suitable production data for wood framing machines.

Tube-tube with weld preparation (63)

System component Tube-tube with weld preparationcut that is made on the part edge in order to enable a more complete weld penetration which provides a stronger joint

includes a new option for the secondary tube:

Rebar in beam (90) and Rebar in beam LT (91)

System components Rebar in beam (90) and Rebar in beamer LT (91) now includes a new drop-down list in the tabs Primary bottom bars, Primary top bars, Side left and Side right:

The system component includes a new option in Tekla Structures 2020 to cut the secondary tube profile and to define the desired angle(s):

For more detailed information about the using the system component, click the Help button in system components dialog box.

Floor Layout

System component Floor Layout includes several improvements.
In previous Tekla Structures versions, system component Floor Layout CIPcast unit type where the concrete is formed, poured, and cured in its final position

filler properties
was included to fill seam gaps between hollow core slabs:

This component is not included in Tekla Structures 2020 anymore because this option is now available in the new tab CIP filler part in system component Floor Layout:

Set the options Create filler parts and Fill seam gaps to Yes to fill the seam gaps:

You also use the option Create filler parts when you use the new options (1) on the tab Advanced to define the conditions for detailing the hollow core slabs:


Create filler parts No
Create filler parts No
Create filler parts Yes

In addition, on the Advanced tab, you have options to define classes (colors) for parts that cut hollow core slabs and that you want to give a clearanceset space between objects

In bolted connections, clearance is required for entering and tightening the bolts with an impact wrench. In addition to this, there may be a clearance for a fillet.

In welded connections, clearances are required in order to allow a welder to lay a correct weld.

Reinforcing bar clearance defines the minimum clearance or the allowed overlap for reinforcing bars when they are checked against other objects.


The classes you enter automatically appear on the Default offsets tab where you can define the size of the clearance:


Wall layout connector

Tekla Structures includes system component Wall layout connector, which you can use combined with the wall layout tools, for connecting walls to each other. The system component is improved and now includes a new button for detailing the shells at the edge connection:

Custom components

Availability of custom components

In Tekla Structures 2020 the availability for custom components has changed.
The availability depends on the so-called "role" with which you start Tekla Structures. These roles have been modified so that you now only have a few obvious custom components.
For example, customers who start Tekla Structures with the Steel Detailer role now have a steel-related custom component and a few general custom components by default. They therefore do not have default wood and/or concrete-related custom components.
In Windows Explorer:

In Tekla Structures:

To have all other available custom components, you can import them in Tekla Structures in the usual way.


Improved drawing performance

The performance of the drawings has been improved in Tekla Structures 2020. The improvements affect drawing opening time, zoom performance, pan performance (dragging the drawing from one end of the screen to another) and drawing editing (adding add marks, text, lines, and moving views, among other things). ​

The advanced option XS_USE_SMART_PAN is now set to TRUE​ by default to be able to zoom and pan even faster. ​

Improved settings for GA- and assembly drawings

GA drawings
Tekla Structures includes GA drawingdrawing that is created from one or more model views and that shows information needed to understand the general arrangement of structural elements on a project

General arrangement drawings show how parts, assemblies, cast units, or pour objects are located in a building.

setting 3D:

In this setting, the Filter defines which model objects are shown in general arrangement drawings:

Welded plates with the name PLATE are deliberately hidden because in GA drawings with scale 1: 100 or larger, it is not useful to show these plates.
In Tekla Structures 2020, this setting has been improved to also hide parts with the name STIF (stiffenercomponent object that represents a structure that strengthens a steel beam or column

Stiffeners are usually plates.

Stiffeners are used to prevent web buckling at supports or concentrated loads.

), NUT and WASH (washer):

Tekla Structures 2019i and earlier versions:


                                         Model                                                                                                 GA drawing

Tekla Structures 2020:


                                         Model                                                                                                 GA drawing
This has also been improved on view level so that the setting 3D GA is now available:

Assembly drawings
For assembly drawings, the settings supplied by Construsoft have been adjusted:

All settings now include the setting 3d assembly in the button View:

for the representation of a 3D view in assembly drawings:

The setting 3d assembly does not use any filters so that all model objects of the assembly are shown in the drawing. ​

New settings for cast unit drawings

Tekla Structures 2020 includes the new settings sandwich-wall and stair for cast unit drawings:

When you use the setting stair, also the new template concrete-stair_info will be used:


CE Marking

CE Marking became mandatory on 1 July 2014 for steel construction parts. To satisfy these requirements, Construsoft made several changes in earlier Tekla Structures versions. To keep satisfying these requirements, in Tekla Structures 2020 the template execution_classpart property that groups parts according to identifiers given by the user

The identifiers of classes are usually numbers. Classes can be used for defining the color of parts in the model, for example. Class does not influence the numbering of model objects.

has been modified:

Earlier Tekla Structures versions:


Adapted layout for templates

The space between the templates template_A1 and execution_class has been enlarged:

so that there is also space between the templates when the template revision is shown in the drawing as a result of revisions.

Customize drawing layouts easily with the improved Layout Editor

In Tekla Structures you can define the drawing layoutplan of a drawing that includes the table layout and definitions of the sheet size

Tekla Structures includes several predefined drawing layouts, which are drawing-type specific. The user can also create new drawing layouts.

and customize the layout. The layout defines which tables are included in the drawing:

1 = Drawing frame
2 = Drawing views
3 = Templates
4 = Table layoutplan that defines the selection, placing, and scale of tables in a drawing

To define the drawing layout and customize the layout in earlier Tekla Structures versions, you could use:

- the command Drawings & Reports > Drawing properties > Drawing layout in the Model Editor:


This command is no longer available in Tekla Structures 2020.

- the Layout Editor. You use the Layout Editor for creating and editing drawing layouts and define the positions for templates.

You can use the Layout Editor for customizing layouts directly, quickly and easily. Because of that, Tekla Structures 2020 provides a new and improved Layout Editor (via File > Editor> Drawing layout editor) where you can customize layouts and define new layouts . All changes you make are shown in real time in the Layout Editor:

NOTE: New drawing layouts in Tekla Structures 2020 are also saved as *.lay files, just like in previous Tekla Structures versions. However, these new * .lay files are not compatible with * .lay files you created using the command Drawings & Reports > Drawing properties > Drawing layout or the Layout editor in earlier Tekla Structures versions. This means that you cannot use the new layout in earlier Tekla Structures versions.


In earlier Tekla Structures versions, the layout was divided as follows, for example the layout ga including corresponding table layouts:

In Tekla Structures 2020, the drawing sizes are defined in the table layouts with the new layout editor:


The following example explains the points of interest when copying layout files (* .lay file) from an earlier Tekla Structures version to Tekla Structures 2020.
Suppose you have created your own layout in Tekla Structures 2019i, in the example below the layout customer:

In here, the following table layouts are defined:

The following template layouts are linked to the Fixed sizes:

As you can see in the images above, the template layout customer_dummy is not linked to any Fixed sizes.
We copy the layout file (*.lay file) customer to Tekla Structures 2020 and open the layout file in the new Layout editor:

Drawing layout customer is selected (1) and you see in the list Drawing size (2) that the table layout customer_dummy which is unassociated, automatically names the size ###_customer_dummy.

(You can now also select to which drawing types (3) you want to apply drawing layouts).

General: In case you open a layout file (.lay) with unassociated table sets created in previous versions of Tekla Structures, Tekla Structures generates a drawing size to every table set automatically, and names the size ###_[TABLE LAYOUT NAME]. The position of the templates in the layout is unchanged. The name and the size need to be checked and, if necessary, you need to modify these.

You must select the unassociated table layout and click the button , the following dialog box appears:

Change the name and the size (column Width and Height) and click OK to save the changes:

... to be able to use the customized drawing size in drawings:

Single command for creating various types of rebar dimension marks

Previously there were three separate commands for creating rebar dimension marks:

The workflow for creating rebar dimensions marks has been simplified in Tekla Structures 2020 so that there is only one command available now in the ribbon in the tab Dimensioning:

... as a command in the context menu:

... and via the function Quick launch:

In addition, Tekla Structures 2020 includes a few new settings for dimensioning:




The style of the rebar dimension markpart of a dimension that displays the basic information about the building object measurements

A dimension mark can consist of a prefix, numerical value, and postfix.

is controlled by the properties on the new Rebar tab in the Dimension Properties dialog box:

- Dimension to specifies whether dimensions are created between All rebars or between the Start and end rebars only. Part edge adds closing dimensions to the edge of the part in reinforcing bar groupgroup of reinforcing bars that are side by side and have identical properties, except the possible variation in bar lengths

dimensions. This setting is only available if Dimension to is set to All rebars.
- Subgrouping specifies whether subgroups are created for different rebar spacings within a rebar object so that dimension marks can display the subgroup properties.
- Extension line(1) line in a drawing that is perpendicular to a dimension line and that connects the dimension line to the building object

(2) temporary line in a model that can be used for aligning objects with each other

(2) Extension lines can be used when snapping or creating points.

to visible rebar
controls the display of extension lines to the visible rebars.
- Tapered dimension type specifies whether skewed dimensions have skewed or horizontal representation.
- Curved dimension type specifies whether curved dimensions have curved or horizontal representation.

For more detailed information about rebar dimension marks, click here.

Display frames of drawing view permanently

In Tekla Structures 2020 (and also from Tekla Structures 2019i SP3 on), you can permanently display the frames of drawing views (and not only when you move the mouse cursor over the frame of a view):

You can add the line XS_VIEW_FRAME_HIDING_DISABLE=TRUE to any *.ini file.

The view frames are not displayed by default in drawings:


BTL Export (ML019) - BVX Export (ML027) - Randek Export (ML077) - BVN Export (ML081)

Tekla Warehouse includes several export tools for generating production data for wood framing machines such as BTL Export (ML019), BVX Export (ML027), Randek Export (ML077) and BVN Export (ML081). These tools are updates frequently because of new functionalities or improvements or fixes:

Macros are located in the applications and components catalog. They are recorded or created manually and stored as .cs file in a folder defined with the advanced option XS_MACRO_DIRECTORY.

Macros can, for example, be used for creating drawings or reports.

Macros are sometimes used to run an application.

Sequence Tool (ML013) by default. You can use this macro to assign user defined attributes (UDAobject property created by the user in order to widen the range of predefined object properties

User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

's) to parts, for example unique control numbers for (foundation)piles, assembly sequences or to sort truck loads by assigning group numbers:

The macro has been improved and now supports items.

For more detailed information about the macro, click the Help button in the macro's dialog box.

Trimming steel (m036)

Tekla Structures includes the plugin Trimming steel (m036) for several versions.

... to position trimmer profiles in hollow core slabs:

The plugin is improved in Tekla Structures 2020 and you only have to pick two points for positioning the trimming profile.

In addition, the tab Support hands in now included where you can define multiple types of hands:

and on the Advanced tab you can define an offset to the picked points:

Slab dimensioning (DR060)

The tool Slab dimensioning (DR060) was included in earlier Tekla Structures versions by default:

... to dimension cladding profiles in a certain way in drawings:

This tool is moved to Tekla Warehouse and therefore no longer available in Tekla Structures by default. In addition, the tool has been renamed to Object dimensioning tool.

The tool can also be used for cladding in a sloped plane, for example a roof plane.

Opening Dimensioning (m061)

The tool Opening Dimensioning (m061) was included in earlier Tekla Structures versions by default:

Tekla Structures 2020 includes the new plugin Rotate Coordinates Of Cross Section (ML087):


You can add fixed profiles to the profile catalog in Tekla Structures by defining the cross section via File > Catalogs > Define profiles > Define cross section using polygon:

Click here for detailed information about adding profiles by defining the cross section via picking corner points of the cross section.

You pick the points of the cross-section in a specific order (1-2-3-etc.) to determine the orientation of the profile.

To change the orientation after defining the profile, so that the profiles are correct regarding to the orientation in the output, such as drawings and export files, you can use the new plugin CS Rotate Coordinates Of Cross Section (ML087).

Steel Frame components

In previous Tekla Structures versions, there were several tools available for steel framing. These tools have been moved to Tekla Warehouse and are therefore no longer available in Tekla Structures by default. Several new tools have also been added and are available:

TIP: Don't forget to set an alert in Tekla Warehouse for the tool to get informed automatically in case the content changes or if a new version is available.

Bolts between points (m093)

The tool Bolts between points (m093) is included in Tekla Structures since several versions to quick and easily model bolt groups:

It is preferred to switch snap option Snap to lines and edges on so that you can snap to the edges of parts. The yellow arrowhead indicates the direction of the bolt groupgroup of bolts that forms a connecting building object between an assembly main part and secondary parts

The number of bolts in a bolt group depends on the bolt group shape and the values of bolt distances.

. If you want to change the direction, move the cursor closer to the opposite end of the line.

The tool is improved and includes new options:

Here you can define the bolt spacing, the number of bolts and the options to divide the bolts in X direction.
