Quite new here, just been using blender for 2 days but seems very intuitive. The only 2 issues I have been finding relate to importing Revit geometry whether IFC or FBX. They come in correct but the vertices are all messed up meaning I cannot subdivide them correctly. Second I do not know how to split faces, as Revit exports walls rather than faces I cannot for example apply a material on the exterior that is different from the interior.
Any help is appreciated.
