Adjust object user-defined attributes for IFC export

If you do not select Spatial hierarchy from Organizer in the IFC export settings, the export uses the IFC export hierarchy defined in the part UDAs. You also need to modify the part UDAs to define the load bearing information, and select the IFC export type.

Double-click an object in the model, for example a column, to open part properties, and click the User-defined attributes button.
Go to the IFC export tab.
To select the IFC export type, in the IFC export type list, select Auto or B-rep.
- The Auto option will automatically select what kind of Swept Solid IFC object a Tekla object becomes in the IFC.
- If Auto fails for some reason (such as with a deformation), the export reverts to B-rep automatically, and creates a mesh-based IFC object with less intelligence. These objects are data heavy but still geometrically correct.
- B-rep will force the IFC object to be always mesh based.
To define part-level IFC export hierarchy, enter values for the IFC building name and the IFC building storey name.
To define load bearing information, go to the Structural information tab and set Load bearing to Bearing. This defines the user-defined attribute LOAD_BEARING for the exported object.

Set this option to No for all non-load bearing objects. Bearing is the default value.
Click Modify in the user-defined attributes dialog.
