Other interoperability improvements

Tekla Structures 2020 contains improvements in IFC4 export, 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.

object conversion, DWG export, Layout manager, and Tekla Structural Designer import, for example. There is also a new model format .tekla available.


IFC4 export

  • Spatial hierarchy from Organizertool that is used for categorizing and managing model information, object properties and object property queries, and model object classification

    Organizer consists of two tools, object browser and categories.

    now supports pour units. Note that objects in the Organizer uncategorized categorycategory where the model objects are automatically placed in Organizer if they are not inside a defined boundary box

    The uncategorized category shows that the location breakdown structure is incomplete. The model objects can be manually moved from the uncategorized category to a chosen location category, or boundary boxes can be changed to move the model objects to the wanted location category.

    are not exported.

  • When you select the option Pours, pour objects and pour units are exported but cast-in-place concretecast unit type where the concrete is formed, poured, and cured in its final position

    parts and cast-in-place cast units are not exported. If you do not select this option, cast-in-place concrete parts and cast-in-place cast units are exported without pour objects or pour units.

  • You can now include pour and pour unitentity that combines together a pour object and the other building objects that need to be in place before cast-in-place concrete can be poured

    The needed building objects can be reinforcement and embeds, for example.

    template fields and UDAs in the IFC4 export. Pour template fields and UDAs are set to IfcBuildingElementProxy and pour unit to IfcElementAssembly in Property Set Definitions. UDAs are set with template field setting using USERDEFINED."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.

  • Now the IFC4 export supports the export of project properties, such as town and country.

IFC object conversion

  • The IFC object conversion now supports multi-geometry conversion and updating.

  • Information of how a profile was detected has been added to the results list in the IFC object conversion.

  • Multi-geometry BREP part IFC object conversion now works also in update.

DWG export

  • It is now possible to cancel the DWG drawing export/preview.

  • Drawing DWG export now handles 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.

    offsets better.

Layout manager

  • In Layout manager, you can now import or export points relative to the current work planeplane that the user has chosen in a model and that is currently active for working on in a model view

    Newly created, copied, or moved model objects comply with the work plane. For example, shifting the work plane to follow a sloped plane makes it easier to model sloped structures.

    in the model.


  • Tekla Structures now supports SketchUp version 2020.

New .tekla model format

  • .tekla model is a new lightweight Tekla Structures model that can be used as 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.

    . It basically enables Tekla Structures model referencing from 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.

    as an overlay model or as a normal reference model.

  • This format lists and visualizes objects, parts, rebars, bolts and assemblies, but not pours or pour units. The format can be created to a Trimble Connect project with the Upload model command.

Import from Tekla Structural Designer

  • The Rebars tab is now available in the Tekla Structural Designer import dialog box. The Rebars tab will only be active if compatible versions of Tekla Structural Designer and Tekla Structures are installed on the same computer and if the original Tekla Structural Designer file (.tsmd) is selected. Currently only the 2020 versions of both Tekla Structures and Tekla Structural Designer are compatible.

    It is no longer necessary to install a separate extension from 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.

    to enable rebar import.

    Use these new settings to define how reinforcement is imported from Tekla Structural Designer to Tekla Structures:

  • Openings in concrete walls can now be imported from Tekla Structural Designer to Tekla Structures.

    Openings in sloped walls are not imported.

  • The option Remove previously imported openings to remove all existing openings that were previously imported from Tekla Structural Designer has been added to the General tab in the Tekla Structural Designer import dialog box.

Base points

  • The base point location in the model can have a maximum value of +/- 10 km from the model originglobal coordinate system point of origin used for the model

    Model origin is the default project base point.

    . Modeling is meant to be done near the model origin, and the offset is to be given with the East coordinate and North coordinate values.

Export MIS

  • The word Fabtrol was removed from the Fabtrol/KISS export user interface texts. So now it only says KISS in the Export MIS dialog box and in the status bar messages.
