BlenderBIM: Relationship between deleted blender materials and Ifc Styles
Hi everyone.
After working for a while in an IFC file, I got a lot of material duplicates in Blender, like "material.001". This also created duplicates of Ifc Styles. When I realized that, I started to clean up the file. However, even after I delete all the materials that are not being used anymore, their IfcStyle data still persists in the file. Then, when I reimport the IFC, all the deleted materials are created in Blender again.
Is there a way I can delete the "orphan" IfcStyles?
Thanks

A huge thanks for bringing this up. This is quite a fundamental omission in the BlenderBIM Add-on's capabilities - there is no way to manage materials. You'd just indirectly add them through objects, but this is definitely not the correct approach.
I've started building a material manager, which will include the ability to delete materials - so when it's built, that's where materials should be deleted from. That also improves upon the rather awkward situation of how you create new materials and manage materials in your library.
Answer here, thanks Dion!
