I have an ifc file from revit mep. I can see all objects in 2d but the simplest objects, rectangular boxes, don't appear in 3d. When I try to cut a section I get the infamous "internal cut error #64". I searched the forum for that message and I don't have any of the conditions, (complex profiles, meshes, seo, etc) that were mentioned in previous posts. ???????? What might be solution?
