I'm manipulating an IFC file, writing it back to IFC with a few changes. So far I couldn't figure out how to write a Material Layer Set. I can see it is defined in the geometry traits of my original IFC file but when I write it back out it seems to remove the information. Has anyone done this?

Geometry traits on original IFC:

Hi @ekkischeffler​,

I'm sorry, but the IFC writer cannot presently write Materials or Type objects. We are working towards a new IFC reader/writer that will solve this problem, but this will take some time to implement.


Thanks @daveatsafe​ for letting me know!
