Export a Tekla Structures model or selected model objects to an IFC file
You can export Tekla Structures model or a part of the model into an IFC file.
Before you start the export:
- Define the IFC entities for Tekla Structures model objects.
- Define the needed property sets.
- If you export the IFC file using the base point, define the base point.
-
To have pour objects and pour units (from Tekla Structures 2018 onwards) in your model, set
XS_ENABLE_POUR_MANAGEMENT
toTRUE
. In the IFC2x3 export, to export pour objects instead of CIP concrete parts select thePour objects check box. In IFC4 export, to export pour objects and pour units instead of cast-in-place parts and cast-in-place pcast units, select the Pours check box. Note that pour unit export is not supported in IFC2x3. -
During the IFC export you can add classification information to assemblies by entering the name of the classification system in the user-defined attributes in Project properties. The classification system is written to the IFCCLASSIFICATION field in the export file. You can define the classification values for the assemblies in Organizer or in the UDA dialog box of the assemblies. Note that classification information is written to the assembly level only.
For more information about how to add classification information to assemblies in Organizer, see How to add classification code to objects in Organizer and export it to IFC.
For more information about adding UDAs to the UDA dialog box, see Define and update user-defined attributes (UDAs).
-
You may want to check and modify the user-defined attributes of the exported parts related to IFC export and structural information.
Define IFC entities for Tekla Structures model objects
Before you export Tekla Structures model objects to IFC, you can define the resulting IFC entities for the exported model objects in the user-defined attributes of the objects.
Export to IFC2x3
Export to IFC4
You can export a Tekla Structures model or a part of the model into an IFC4 file.
Before you can start the IFC4 export in
Tekla Structures, you need to set the advanced option
XS_IFC4_EXPORT_PLEASE
to
TRUE
in
teklastructures.ini.
After the export a message box is displayed. In this message box you can select to open the folder where the exported IFC model is stored, or view the log file in a browser. The log file gives detailed information of the export process, exported entities and the errors occurred during the export.
Limitations in IFC4 export
- The export is not certified by buildingSMART and may therefore have syntax and content issues.
- The user interface does not provide all the features included in the IFC2x3 export user interface.
- The Reference view is intended to be used for design coordination and for referencing workflow. Due to the API change, all the needed pieces of data may not be available and therefore the resulting IFC model may be incomplete.
- We do not recommend using IFC4 in production projects yet.
