I dont know if this is a bug or what but we went from this feature "split Toposolids" not working to... somewhat working?, I still get the error messages and now clicking "delete" the split toposolid now actually works. the Rectangular shape is the split toposolid.
Someone at Autodesk forgot to code in a new message perhaps or do we just use the "delete" button as confirmation now?. Lol.
