I'm currently working on a large model in AutoCAD and I'm working with 3d faces. I have a collection of roughly 700 regions but I'm unable to SURFSCULPT. It says there is no watertight volume, which I know means there is a gap in the geometry somewhere. I've attached the file below if anyone can help me out.&nbsp;</P> Mon, 18 Jan 2021 04:30:06 GMT Anonymous 2021-01-18T04:30:06Z https://forums.autodesk.com/t5/autocad-forum/autocad-2020-find-gaps-in-3d-face-geometry-on-a-complicated/m-p/10008864#M87647 <P>Hey AutoCAD forum.
