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.
