These are multiple copies of the same beam.
I know about this problem, but is there a way to manually make all these beams have separate IfcExtrudedAreaSolid/Depth values?
I tried this
but it threw an error.
I also tried to change the GUID.
@theoryshaw the copy class is the right way to go. What is the error you got when you tried to copy the class?
Thanks. It was a pretty messy file. I had imported another IFC file (was an asset file) onto of the base ifc file, and tried to clean it up. Probably not worth sharing.
