That can happen when you have bad geometry or when you have very short edges.

Share the SKP file and we’ll probably be able to help you out.

The “error” disappeared after I applied a paint to an object…? not sure what was going on but it seems to be fixed now.
Thank you

Somehow I’m skeptical that applying a material fixed it. I expect that the problem is still there or SketchUp deleted the bad geometry.

I think the error disappeared when the validity checker fixed it.
