New options in the side pane

Tekla Structures 2021 includes several new options in the side pane.
 

Command Visualizer expanded

In the side pane, in the Visualizertool that creates photorealistic renderings of the model or selected model objects and can be used for taking screenshots and creating animations that demonstrate the design and build options of the model

Trimble Connect Visualizer shows the model’s material types and sets it in a scene.

command in the tab Phases, you now have a new list box in which you can select at which level/part you want to visualize the phases. The option Assembly is still the default option:

Filtering by phases did not always work correct. This has now been fixed. 
The command Visualizer in the side pane now includes a new tab Attributes. Here you can see which variables, but also which user-defined attributes have been defined.

By getting the attributes of a selected part (button Get attributes), these will be displayed, and you can filter the attributes:

Besides  you can also use the search term “or”:

Construsoft Online added

In Tekla Structures, you can run various commands in the side pane, such as accessing the Applications & components cataloguser interface for displaying or modifying information in categorized lists

For example, profile catalog and shape catalog are catalogs.

or adding reference models and point clouds.
 
The side pane has been expanded in Tekla Structures 2021 and now includes Construsoft Online:

This is the link to the Construsoft Supportdesk (Topdesk) where you can find a large collection of frequently asked questions, tips and news. In addition, you can create notifications and view the status of your notifications.

To have access to this service, log in with your Topdesk account. If you are not logged in, you will only see two tiles. If desired, you can change the language in Construsoft Online.

The Construsoft Supportdesk contains many references to articles 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.

(TUA) where all information is in one place; you can quickly find the information you need by using the search function.

The Construsoft Supportdesk is maintained continuously by Construsoft and kept up to date. If new articles are added by Construsoft, for example if news is available, an exclamation mark automatically appears when you start Tekla Structures:

Once the article has been viewed; the exclamation mark will automatically disappear.

New timber related ribbon available

When you start Tekla Structures 2021 with the Timber Detailer role, the ribbon now includes an extra Timber tab:

In addition, the properties of the model objects now include the new group Timber with associated fields:

Copy the ribbon
 
You can copy your customized ribbon from an older Tekla Structures version to Tekla Structures 2021.
 
NOTE: If you copy your customized ribbon, new available (in Tekla Structures 2021) command buttons will be missing, for example the new command Batch-editor in the Model Editor for quickly copying all edits from a source assembly or cast unit to specified target assemblies or cast units in one go:

You can also first compare the "old" ribbon with the new "standard" ribbon in Tekla Structures 2021 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 2021 ribbon, for example the new Batch-editor 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\

Messages for path references to non-existing folders

In Tekla Structures 2021 a message appears in case one or more 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.

refer to non-existing folders: 

Make sure the folder is in the concerned location or correct the path reference for the affected advanced option(s). Next reopen the model.

Adjusted profile database for hollow core slab profiles

For modeling hollow core slabs in earlier Tekla Structures versions, you could use various hollow core 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.

profiles from different suppliers (such as VBI, Dycore, Structo etc.):

Since Tekla Structures 2020 Service Pack 3, these profiles are no longer available in the default 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.

.
It is possible that there are changes in the hollow core slabs, for example changes in hollow core slabs dimensions, hollow core slabs that are no longer available, etc..
 
In order to provide Tekla Structures users with the latest developments, more often suppliers are making their products 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.

. The suppliers are of course responsible for their products.
 
To model hollow core slabs that are not supplier related, from Tekla Structures 2020 Service Pack 3 on, some "fictitious" hollow core slab profiles are available:

The components and tools with which you can model and edit hollow core slabs have also been adjusted in terms of settings, such as the Floor Layout tool:

...and also system components Area filled with slabs (61) and Area filled with slabs (62). The accompanying file pasplaat.dat has also been modified:

If you want to use the fittingadjustment of a part end

plates file with the various suppliers, it is now available with the name fitplates_diverse.dat  and stored in the folder: ..:\TeklaStructures\2021.0\Environments\ConstrusoftEuropean\Config.

Value field LENGTH adjusted in several reports

In Tekla Structures 2021 the value field LENGTH in the following reports has been adjusted to LENGTH_GROSS. The reason is the profiles with a double cut (fit part end + line cutcut that is defined by a cutting line

) so that the longest length is listed.
 
● PDF-material-list.pdf.rpt
● PDF-material-state-list.pdf.rpt
● PDF-saw-list-part-assembly.pdf.rpt
● material-list.rpt
● material-state-list.rpt
● profiles-list.rpt
● saw list with angles.rpt
● saw list part assembly.rpt
● saw list.rpt
 
New report to be able to quickly select the profiles with a double cut: id_part-list-double-cut.rpt.
 
As a result, the so-called gross length is now shown in the reports:

In the drawing:

 

  In case you have customized such reports or created reports of your own in earlier Tekla Structures versions, check them and adjust them if needed (after copying them to your Tekla Structures 2021 TS folder) so that they are up to date again in Tekla Structures 2021.

New predefined rules available in the Template Editor

Tekla Structures already included 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:

Besides the predefined rules Tekla Structures 2021 now also includes several predefined formulas (as a basis) in value fields in the Template Editor.

In a template or list, double-click a value field. The following dialog box appears:

Next click on the button Formularule stated in a mathematical language

Formula is part of an equation.

, you can now select a predefined formula from the drop-down list:

When you select a formula in the drop-down list, the content is entered directly:

All modifications, for both rules and formulas, are stored in the file rules.txt in the folder:

C:\TeklaStructures\2021.0\Environments\ConstrusoftEuropean\General\template\settings

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

Interoperability

New tool CS IFC Extender (ML126)

Tekla Structures includes the option to export a Tekla Structures model (or a part of it) to an 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.

file.
 
For this export, default property set are available in which you can define which attributes you want to include in the export to IFC. Click here for more detailed information about defining property sets for export to IFC.
 
However, in the export to IFC, some attributes are filled in in a certain way but you possibly may want to have another value for some attributes for the purpose of some agreements that have been made regarding to exchanging information, or fields that cannot be filled in by default in Tekla Structures.
 
For this, the tool CS IFC Extender (ML126) is now available. The tool is available in the Applications & components database:

In the tool CS IFC Extender (ML126), the tab IFC Export includes the same options as in the Export to IFC dialog (via File> Export> IFC):

When you create an IFC export in Tekla Structures:

...by default, the material group and the material grade are included in the IFC file:

You possibly may want to include only the material grade in the IFC:

For this, in the Advanced tab you can enable the option Export material grade only:

In addition, on the IFC Type tab in the tool, you can choose per IFC entity on part level which PredefinedType this should be. You can find the IFC entity in Tekla Structures in the IFC export tab:

In Tekla Structures (make sure the button Select objects in components  in the Selection toolbar is enabled):

In the tool CS IFC Extender (ML126), the IFC entity IfcColumn should be PredefinedType PILASTER:


 
In the IFC:

In addition, on the IFC Type Assembly tab in the tool, you can choose per IFC entity on assembly level which PredefinedType this should be. You can find the IFC entity in Tekla Structures in the IFC export tab:
 
In Tekla Structures (make sure the button Select assemblies  in the Selection toolbar is enabled):

In the tool CS IFC Extender (ML126), the IFC entity IfcElementAssembly should be PredefinedType RIGID_FRAME:

In the IFC:

When you make the above changes (such as the PredefinedType for the IFC entity IfcColumn in the example above) by using the tool CS IFC Extender (ML126), this applies to all parts that include this entity.

However, in Tekla Structures 2021 you can now also adjust the PredefinedType by part or by assembly instead of all parts or assemblies with a certain entity. In Tekla Structures, in the user-defined attributes of parts in the IFC export tab, you have a new field IFC entity user type on part level and IFC usertype assembly on assembly levelassembly’s place in the assembly hierarchy

The assembly level is expressed as a number.

in the IFC export tab:

                            User-defined attributes for part                                                                     User-defined attributes for assemblies

You can also adjust the IFC entity by part or by assembly in Tekla Structures 2021. In Tekla Structures, in the part user-defined attributes in the IFC export tab, you have a new field IFC entity user at part level and IFC user assembly at assembly level in the IFC export tab:

The IFC export tab has also been rearranged and regrouped.

You fill in these fields in the user-defined attributes of the part or assembly based on the values which are available in the IFC Type tab (for parts) or IFC Type Assembly tab (for assemblies) in the tool CS IFC Extender (ML126), for example:

The user-defined attributes of the part in Tekla Structures:

In the IFC:

When you create an IFC export from Tekla Structures via File> Export> IFC, for some entities there is no option to change these. For example, description of the assembly (1) that is currently not filled in, or the tag of the assembly where you might want an article number (2).

On part level, for example the description of the part (1) where you might prefer something else.

In the tool CS IFC Extender (ML126) you can use the IFC property mapping tab for this. In here you can write the content of a user-defined attributeobject 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.

in Tekla Structures to a specific IFC property per IFC entity.
 
In the example below, we have entered the following user-defined attributes at assembly level in Tekla Structures:

At part level we have entered the following user-defined attribute:

In the tool CS IFC Extender (ML126) we have defined the following:

When you enter user-defined attributes in Tekla Structures, you must next enter the name of the user-defined attribute in the Attribute column.
 
For more information about user-defined attributes value fields, check this article.

In the IFC:

Modeling

Selecting part by using the crossing selection

In Tekla Structures 2021, selecting parts with a crossing selection works differently than in previous Tekla Structures versions when the parts display is set to Parts wireframe (Ctrl + 1) or Parts shaded wireframe (Ctrl + 2) and the component part display is set to Components wireframe (Shift + 1) or Components shaded wireframe (Shift + 2), to select the objects from right to left that are completely or partly in the rectangular selection area.
 
Earlier Tekla Structures versions:

Tekla Structures 2021:

In Tekla Structures 2021 SP1 it will work as it did in earlier Tekla Structures versions.

Batch editing of assemblies or cast units

In Tekla Structures 2021, you can now quickly copy all edits from a source assembly or cast unit to specified target assemblies or cast units in one go. The new tool Batch-editor reduces the amount of repetitive work in situations where you need to edit identical assemblies or cast units by modifying the object geometry or by changing the part properties:

Batch editor works with identical assemblies and cast units that have the same position numberidentifier that is assigned to all similar parts, assemblies, cast units, or reinforcement

Position number consists of a prefix, separator, and running number. The prefix is part of the position number, identifying a numbering series. The running number is part of the position number, and is the assigned number in the numbering series, based on the start number. The separator is an optional character, such as a slash, that separates the prefix and the running number.

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

In the US, the term piece mark or ship mark is used to refer to a position number.

, or with very similar but differently numbered assemblies and cast units.

For detailed information on how to use the new Batch-editor, see the Release Notes Tekla Structures 2021.

Click here for a steel-related video about the Batch-editor.

Click here for a concrete-related video about the Batch-editor.

Print PDF reports in color

You now have the option to print PDF reports in color:

For this, in Tekla Structures 2021 the setting report is available in the Print Drawing dialog box (Shift + P). You can set the print option to use in the Color drop-down list:

Next click the Save button and print the desired PDF report (s). By default, the PDF reports supplied by Construsoft do not include colors, but you can adjust them in the Template Editor if desired.

As an example, the report PDF-material-list.pdf has been modified and shows a material quality not equal to S235JR in a red color:

Adjusted names of the Construsoft tools in the Application & components database

The names of the Construsoft tools in the Applications & components database have been adjusted:

In addition, many tools have also been renamed in the dialog box so that they now match:

System components

Tensioner central gusset (18)

Tekla Structures includes 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

Tensioner central gussetcomponent object that represents a plate that connects braces to a beam, column, or base plate

(18)
for creating a gusset 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.

to connect bracing bars:

System component Tensioner central gusset (18) has now been taken over by Tekla. You can still use the Willems Anchor and Detan settings in the system component.

As Tekla took over the system component, note the following:

When you created settings for system component Tensioner central gusset (18) in earlier Tekla Structures versions, these settings were saved as follows:

<name_setting>.j90000018

So, the file extension was *. j90000018.

From Tekla Structures 2021, the settings are saved with file extension *. j80000018.
 

  This means that you have to rename the file extensions of the settings you created in earlier Tekla Structures versions to the new file extension (after copying them to your Tekla Structures 2021 TS folder) so that they are up to date in Tekla Structures 2021.

In addition, the settings of system component Tensioner central gusset (18) can be applied in system component Tensioner brace and compression bar (13):

Again, when you have created settings for system component Tensioner brace and compression bar (13) in earlier Tekla Structures versions, you must save these settings once so that they are up to date in Tekla Structures 2021.

Stiffened end plate (27)

Tekla Structures includes system component Stiffened end platecomponent object that represents a plate welded perpendicular to the end of the component secondary part

(27)
. In Tekla Structures 2021, the default settings have been adjusted so that they now work correctly for a column-beam connection and a beam-beam connection:

Earlier Tekla Structures versions:

In addition, system component Stiffened end plate (27) includes new options for creating sink holes by using database file sinkholes.dat. For detailed information, see chapter New options for sink holes in system components.
 
Also, the following has been adjusted in Tekla Structures 2021: When you rotate the secondary part(1) part that exists in a building object and that is connected to the main part

(1) Secondary part can be an assembly secondary part or a cast unit secondary part.

(2) input part that the user selects after selecting the component main part when creating a component

(2) A component can have none, one or more component secondary parts.

(UNP in the image below), the height of the secondary plate is automatically adjusted to the height of the secondary part:

To adjust the height of the plate, enter a value in the field b on the tab Parts for the front plate:

In addition, a 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.

was created in earlier Tekla Structures versions, if a value, for example, "10" was entered for the stiffener thickness, but also if no value was entered:

This has been changed and a stiffener is now only created in case a value has been entered for the stiffener thickness. If no value is entered, no stiffener is created:

In Tekla Structures 2021 also the gapany space between two objects

The term gap is used in its general sense in Tekla Structures.

size for the end plate on the secondary beam has been fixed:

The gap size defines the limit value for the gap between the end plate and the secondary beam. Use this when the beam is slightly curved or sloped to decide if the end angle is so small that the beam end can be straight. If the actual gap is smaller than this value, the end of the beam is left straight. If the actual gap is larger than this value, the end of the beam is fitted to the end plate.

Also, a modification has been made to the command Create AutoConnections. In AutoConnectiontool that creates connections with predefined properties in certain framing conditions

(and also AutoDefaultspredefined properties that AutoConnection uses when creating connections

) is defined which component should be used in which situation. In Tekla Structures 2021, in AutoConnection system component Clip anglecomponent object that represents a right angle that is made of a standard L-shaped profile and that connects parts

(141)
has been replaced by system component Stiffened end plate (27).

Click de following links for detailed information about the usage of commands AutoConnection and AutoDefaults.

New options for sink holes in system components

The following system components now include a new option for using and defining sink holes by using data filefile that contains options for object properties

Data files contain information used by certain components or the rebar shape manager, for example.

Data files have the file name extension .dat.

sinkholes.dat:
 
Joining plates (14)
Column - 2 beam (14)
Stiffened end plate (27)
Seating cap 1 (37)
Seating (39)
Haunchcomponent object that represents a wedge-like structure that strengthens a beam at its end

(40)

Cranked beam (41)
Partial stiff end plate (65)
Two sided end plate (142)
End plate (144)
Footplate (1029)

Some of these components, such as Stiffened end plate (27) now include the new tabs Holes - end plate and Holes - front plate to separately define the sink holes for the end plate and the front plate.

System components Joining plates (14), Stiffened end plate (27), Two sided end plate (142), End Plate (144) and Cranked beam (41) include supplied settings for which sink holes are defined, except for the setting standard.
 
These holes have been set in consultation with a number of customers, taking the welds into account so that they do not collide with the holes and to have enough space for the weld.


 

  In case you have created settings for the above mentioned system components in earlier Tekla Structures versions, check these settings and update them if necessary and then save them again (after copying them to your TS folder in Tekla Structures 2021) so that they are up to date again in Tekla Structures 2021.

To apply sink holes, select the option Data file in the drop-down list. The corresponding values for the sink holes are displayed immediately. The values are grayed out because they are read from the sinkholes.dat data file:

This file is stored in the folder ..:\TeklaStructures\2021.0\Environments\ConstrusoftEuropean\General\profil:

How does this file work? First, in this file, the secondary profiles are defined per line (1) using wildcards, followed by the sinkhole option and the positions and diameters of the sinkholes. For example, secondary profile HE? 140 can be a HEA140 profile but also a HEB140 profile. When the corresponding setting is loaded in the system component, the sink holesmall hollow open throughout a part or assembly that is usually used for fastening parts with bolts or other such objects

Hole is created in the same way as bolts and hole properties are defined in the bolt properties.

positions (3) correspond to the values defined in the file sinkholes.dat:

In the file you see the value 3 in the second column. This value refers to the sinkhole options in the drop-down list:
 

Option In the drop-down list
1
2
3

The following values in the lines are the horizontal distance, the vertical distance, and the hole diameter. The values are defined twice because 4 sink holes are created.
 
You can modify the data file sinkholes.dat as needed and save it in the folder ..:\TeklaStructures\2021.0\Environments\ConstrusoftEuropean\General\profil or in a folder defined by the advanced option XS_FIRM or XS_PROJECT.
 
In addition to the data file sinkholes.dat, you can also select the option Default or Dialog from the drop-down list. Select one of the options in the drop-down list (1) so that you can change the entered values (the values you now see correspond to the values in the data file):

For example, when a beam is positioned skewed and you only want to adjust the position of the holes in the y direction, for example, the value of 125 mm becomes 135 mm.
 
As you can see in the image above, values are entered in three fields for the holes (2). For the three empty fields (3) counts the following: if nothing is entered, the entered value of (2) is the default for that empty field.

On the tab Holes - front plate, no values are defined for the sink holes because this plate not always includes sink holes. You can of course adjust/define this as needed.

New online Help files available

The in Tekla Structures (by default) available system components Tensioner central gusset (18), CS Timber Roof Net Panel (m025) and CS Roof generator Net (m072) and the Tekla Warehouse tools Wooden roof (m150) and Detail numberingprocess of assigning position numbers to parts, cast units, assemblies, or reinforcement

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

(m135)
now include an (online) Help file:

The Help files are located in the Tekla User Assistance 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 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.

(57)
for creating (prefab) timber walls, floor elements, metal 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.

frame structures, etc., now includes several improvements:

In case you are using an extra stanchion at the location of a seam in Tekla Structures 2021, the extra stanchion can be shortened with the new Shorten option on the tab Stanchion Parts2 where this value is distributed between the bottom and the top side of the extra stanchion:

System component Wood wall (57) already included the option to indicate that battens needed to be shortened. This worked correctly for reports but not for the export to the machine control. For this, the battens have to be shortened physically. That is why you now have an extra option Physically.

The “old” method By 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.

:

The new method Physically:

In addition to the already existing options By number and By spacing stanchion for the distribution of the stanchions, the option Center to center is added. This has the advantage that with different widths for the beams, this does not affect the distribution:

A BTL framing option was previously available on the BTL tab. This setting ensured that the element was not created as 1 whole element, but as 1 super element with various sub-elements. This working method could not be used if the element was exported as BTL for machine production, but also not for the default method of production drawings as supplied by Construsoft. Conclusion: Actually, this function should not be used, that is why it has been removed:

Earlier Tekla Structures versions:

Tekla Structures 2021:

In addition, the functions that were available on the Connection tab were no longer used and therefore the tab has been removed:

A number of fixes have also been implemented:

● If a horizontal and a vertical batten were selected in the same layer, the intermediate battens must be shortened for ventilation purposes. This did not always work correctly and has now been fixed.

● Sometimes it was not the bottom batten that was the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

(1) Main part can be an assembly main part or a cast unit main part.

(2) input part that the user selects first when creating a component

(2) Connections and details always have a component main part.

of the element, but the left stanchion. This has now been fixed.

● In some cases, the distances of the openings were not properly calculated. This has now been fixed.

● The distribution of the plates from the left sometimes resulted in an unexpected distribution of the plates. This has now been fixed.

Stringer stanchion Lprof (68)

In earlier Tekla Structures versions, there were two system components Stringer stanchion Lprof (68) available to connect stanchions to the stringer:

In Tekla Structures 2021, the Construsoft system component has been merged with the Tekla one so that the system component is available now only once in the Applications & components database:

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

System components Rebar in beam (90) and Rebar in beam LT (91) include a new interface so that they are clearer and more structured and have a more logical layout.
 
Tekla Structures 2021:

Earlier Tekla Structures versions:

Now on all tabs, the parameters that belong together are now grouped together and can be found in the same place. The generation method (1) is shown in all tabs as the first option at the top left in the dialog box:

The images have also been adjusted (if necessary) so that the parameters associated with an image are now clearly visible and you can now define the bar properties on the tab itself for the relevant bars/stirrups (and no longer on the tab Advanced):

In addition, there is a new tab Extra primary bars available in which you can define additional primary bars:

The extra bars are created at the location of a concrete part that you define based on the name or 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.

of that part.
 
Suppose you have added a pour to a concrete beam with the name POUR:

In the tab Extra primary bars, you can now define this name (1) and the properties (2) of the extra bars:

Border rebar (92)

Tekla Structures includes system component Border rebar (92) for modeling border rebars in concrete parts. The generated reinforcement consists of edge bars and hairpins that are placed both on the edge of the element and around a recess.

In case you have created settings in previous Tekla Structures versions for system component Border rebar (92) and you load these settings in Tekla Structures 2021, you may see certain values in some fields, for example a diameter with decimals or the value -2147483648.000000:

This is the result of a change that has been made to this component in Tekla Structures 2021.

The value -2147483648.000000 represents an empty field if nothing was entered for that field in the setting from a previous Tekla Structures version.

So, when you load settings from earlier Tekla Structures versions into Tekla Structures 2021, you must check all tabs per setting and adjust such values or clear the field. Next you save the new setting via the Save as button.

For detailed information about the usage the system component works, click the Help button in the system component's dialog box.

Changing options in (reinforcement) system components

Changing some options in particular reinforcement system components works differently from earlier Tekla Structures versions.

Sometimes you cannot immediately define and change the desired number. Sometimes you need to define a different diameter before you can apply the desired number.

Footplate (1029)

In addition to the improvements made in earlier Tekla Structures versions, system component Footplate (1029) also includes several adjustments and improvements:
 
System component Footplate (1029) includes new options for creating sink holes by using database file sinkholes.dat. For detailed information, see chapter New options for sink holes in system components.
 
In earlier Tekla Structures versions, when using sinkholes, these sinkholes were also created in filler plates. This has now been fixed.
 
In addition, the tab Anchors now includes the new field Finish for the anchors and the cast plate:

In addition, you now have the values CPLATE and BPLATE for the anchors, the cast plate and the base platecomponent object that represents a plate welded to a column base

Base plates are used to distribute the concentrated load of the column over a wider area.

when you inquire the information of a part (Shift + I), for example from an anchor:

You can use these values in templates and reports to show the information.

In addition, you can use the values for calculating in formulas: in the anchor_list.doc list, for example, these values are used:

  

When you start calculating with the values and you have entered the following in the fields below:

...the values are shown when you inquire the information from an anchor:

  

Next you can use the values, for example in the anchor list. You open the list in Template Editor and add a value field (or edit an existing value field), next use a formula:

Next when you generate the anchor list, the value (which is the result of the formula) is shown (34 + 33 + 12 - 2):

With regard to useability, the tab Parts now includes a new drop-down list for defining the chamfer settings of the base plate, one chamfer per corner or the same chamfer for all corners:

In earlier Tekla Structures version, in some cases the chamfer was not calculated correctly. This has now been fixed.

Custom components

Speed improvement for custom components

In Tekla Structures 2021 includes some speed improvements when applying custom components.

Mostly custom components that consist of many parts, such as custom components for railings, save a lot of time.

Delete custom components from the Applications & components database

In earlier Tekla Structures versions, deleting custom components from the Applications & component database sometimes did not work correctly. This is fixed in Tekla Structures 2021:

Drawings

Modified template foils

Tekla Structures includes the template foils for several Tekla Structures versions to show the overlap per side of the foil in elements in the drawing:

The template is stored in Tekla Structures 2021 in the folder ..:\TeklaStructures\2021.0\Environments\ConstrusoftEuropean\General\template.

In earlier Tekla Structures versions, you defined the foil overlap in the assembly drawingdrawing that shows fabrication information for a basic or a nested assembly, including bolts and welds, and that is generally used at the workshop

Assembly drawings show how parts are located in an assembly. They contain the parts of the assembly presented in one or more views.

user-defined attributes:

From Tekla Structures 2021 on, you can also define the overlap at the assembly level of the element in the model. To do this, do the following:

1. In toolbar Selecting, switch the button Select assemblies on.

2. Double-click on the concerned assembly and next click the button User-defined attributes:

3. Define the foil overlap so that it is automatically displayed in the template foils in the drawing. ​

Copying drawing views in general arrangement drawings changed

Tekla Structures includes the option to copy and to link drawing views from one general arrangement 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.

to another.
 
Link drawing views
 
When you link a view from general arrangement drawing G1 with general arrangement drawing G2:

... and general arrangement drawing G1 is modified, these changes are also made in general arrangement drawing G2.
 
If you delete general arrangement drawing G1 in the Documentmanager, the view in general arrangement drawing G2 is also deleted.

Copy drawing views

When you copy a view from general arrangement drawing G1 to general arrangement drawing G2:

... and general arrangement drawing G1 is modified, these changes are not made in general arrangement drawing G2 because the copied view is not linked.
 
If you delete general arrangement drawing G1 in the Documentmanager, in Tekla Structures 2021 the view in general arrangement drawing G2 is not deleted. For this, the advanced option XS_CREATE_CONNECTION_WHEN_COPYING_DRAWING_VIEWS is set to FALSE.

In earlier Tekla Structures versions, the advanced option was set to TRUE which resulted in deleting the view in general arrangement drawing G2.

Adjusted rotation section views in drawings

Tekla Structures includes the advanced option XS_ROTATE_CUT_VIEWS (via File > Settings > Advanced options category 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.

) to specify the rotation of section views. This only applies to section views that Tekla Structures creates automatically. Manually created views have the same rotation as the view they are created from.

The advanced option has been changed in Tekla Structures 2021 and is now set to BY_SYMBOL_MAIN_VIEW:

Defines the rotation of a section by the orientation of the view whose section symbol of the section is located:

In earlier Tekla Structures versions, the advanced option was set to BY_MAIN_VIEW by default.

The rotation of all section views is the same as the orientation of the main viewdrawing view that shows all parts in an assembly, cast unit, or single-part drawing from the selected viewing direction

Main view can be front view, top view, back view, or bottom view. The user can create several main views.

Improved dimension rule associativity

Tekla Structures includes associativitydrawing property that represents the linking of drawing objects to model objects so that the former are updated according to changes made to the latter in the modeling mode

In Tekla Structures, associativity only relates to one type of drawing objects, namely associative objects. These can be building objects and associative annotation objects.

In Tekla Structures, the term associativity has traditionally been used when referring to the linking of drawing objects to model objects. In other modeling contexts, however, the term associativity may refer to any kind of linking between model objects or parts of a model by using dependencies.

for dimensions since several versions:


 
Each dimension pointpoint that Tekla Structures or the user has used for dimensioning

associativity symbolgraphic that Tekla Structures creates in a drawing and that indicates that an associativity point of a drawing object is associative

The associativity symbol changes if the associativity point is not associative.

includes a list of objects with available associative locations. As you can see in the image above, you can link the dimension point to the beam or to the welded plate.

It may happen that the locations of the dimension points are unclear, for example in a sandwich panel where there may be several objects in the same point location:


 
In earlier Tekla Structures versions, dimension points were associated by default with the objects that the dimension points were added to when you manually dimensioned.
 
From Tekla Structures 2021 onwards, you can select an associativity rule for each dimension point during the manual dimensioning of the drawing objects. Now you can properly associate a dimension during its creation, and the dimension locations are preserved better during drawing updates and cloning.

To activate the new dimension creation associativity functionality, go to File > Settings in the drawing modemode that is used for editing the appearance and content of drawings

Tekla Structures switches to the drawing mode when the user opens any drawing.

, and in the Switches section, select the Dimension creation associativity check box.

Next start creating a dimension. Pick the dimension point position, and the associativity rules list is displayed each time when a point with available associativity rules is detected.
In the example below, the dimension point can now be linked to the plate or to the beam:

Adjusted representation for reference models in drawings

You can represent reference models in drawings by using the options Outline or Wireframe:

In earlier Tekla Structures versions, the hidden lines of model objects were not turned off correctly or represented as dotted lines behind reference models in case the setting Outline was applied. The following example shows a structure consisting of Tekla Structures model objects and a wall as a 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.

:

This has been solved in Tekla Structures 2021 and the hidden lines of model objects are correctly turned off or represented as dotted lines behind reference models.

The hidden lines are turned off:


The hidden lines are dotted:

Representation view labels in single part drawings for parts

Now view labels are represented by default in single part drawings for parts:

For this, the option in the Mark contents dialog box is set in the single-part drawingdrawing that shows fabrication information for one part and that is generally used at the workshop

properties dialog box:

If desired, you can adjust the content of this label content.

Location of images in templates changed

The location of the images used in templates in drawings has been changed so that the environment ConstrusoftEuropean is complete after installation. The files are now stored in the folder:
 
..:\TeklaStructures\2021.0\Environments\ConstrusoftEuropean\General\template\bitmaps
 
In earlier Tekla Structures versions, the images were stored in the folder:
 
..:\TeklaStructures\<version>\nt\bin\TplEdtool in Tekla Structures that is used for creating and modifying templates to be used in drawings and reports

\bitmaps

Adjusted rebar dimensioning marks

Since Tekla Structures 2020 you can use the command Rebar in the ribbon for creating various types of rebar dimension marks:

This command is also available in the context menu and via the function 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.

.

The properties dialog box of the Rebar command includes various settings for the dimension marks by default:

See the Tekla Structures 2020 Release Info for detailed information about these settings (chapter Drawings > Single command for creating various types of rebar dimension marks).

These settings have all been adjusted so that the placing is now set to Fixed:

This allows you to pick the location by yourself when creating the dimension lineline that visualizes the distance between the defined dimension points

Separate dimensions can be combined into a longer dimension line.

.

In earlier Tekla Structures versions, the location of the dimension line is determined automatically because the placing was set to free.

You can also customize the appearance of the reinforcement groups, for example of a reinforcement meshreinforcement that represents a mesh of steel bars in two perpendicular directions

In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

the longitudinal and the crossing bars in a separate color:

Simple plate (m131)

Tekla Structures now includes the new tool Simple plate (m131) to quickly and easily model contour plates:

For optimal use of the tool, make sure that the command Direct modificationfunction that activates the mode where the model objects can be modified by using handles

Direct modification enables additional handles and modification options.

  (shortcut D) is enabled.

You can model a contour platepart whose outline form the user defines by picking three or more points

The user can define the shape of the contour plate parallel to the work plane. The profile in use defines the thickness. The corners of the contour plate can be chamfered.

by picking 2 or 3 points.

2 points: You pick the first and the second point:
