Other interoperability improvements

Tekla Structures 2020 contains improvements in IFC4 export, IFC 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 Organizer now supports pour units. Note that objects in the Organizer uncategorized category are not exported.

  • When you select the option Pours, pour objects and pour units are exported but cast-in-place concrete 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 unit 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."UDA".
  • 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 point offsets better.

Layout manager

  • In Layout manager, you can now import or export points relative to the current work plane 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 model. It basically enables Tekla Structures model referencing from Trimble Connect 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 Warehouse 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 origin. 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.
