if you create a compound with upgrade or part compound, it works. in my opinion that is enough to take part in a bim process based on geometry without any attributes.

923.ifc

To the best of my knowledge I'm using the default IFC Import settings and using the build below, the original file imports error free:

thank you for your cooperation. I also tested it with 0.19-3 and 0.18. apparently it works better on windows than on linux.

Cool ! Did you compile the ifcopenshell ? Or some way to use the "built-in" in the AppImage?

Can you report it in the Mantis BugTracker ?

Thanks

i can't remember compiling it. i compile very little because i often have problems with it.


I think it's from here

http://ifcopenshell.org/ifcconvert

how do i report it in the bug tracer?

is there an instruction?
