IFC export of facebinder objects

Post by bernd »

The CAD we gone use at work is not able to extract faces from solids easily. I need a lot of faces from solids for a project. My idea was as follows.

- export the building model from Allplan as ifc
- import the model in FreeCAD
- create facebinder from solids for all neded faces
... works great so far

- export the facebinder faces to ifc --> the exported ifc is empty :(
- import ifc in Allplan

Does ifc export support export of faces ?

cheers bernd

I think facebinder is like a Draft element (Dwire). They cannot be exported as ifc files, yet.

In older versions of Freecad (Freecad 0.19) it was possible to export facebinder geometry directly to ifc file. In ifc, the facebinder was correctly displayed as IfcBuildingElementProxy with face geometry. I haven't found a way to export facebinder geometry to ifc in newer versions. Maybe I'm doing something wrong. Otherwise, it would be great to restore this posibility again in newer versions. Thank you so much for the reactions.

Welcome @Jan6512 :)

Can you file a bug report following the bug reporting guideline please ? Much better for developer to avoid missing it out.

It is not a problem of the facebinder object. Faces at all are not exported as geometrical objects. A facebinder is a face.

Examples attached ... The line objects in the ifc are just annotations and not real objects.
