I modifies the attached file in SU 2017. It looks fine to me. When I import it into my printer software and preview it before I send it to my printer, it looks like it has added a cover on top of the piece as well as other junk within the drawing. None of this shows on the Sketchup drawing. I don’t know what to do to clear this up. Can you help me please. If you can fix it, great but please let me know what you did so I can learn form it.
The one that shows the excess geometry is not a solid in SketchUp. Perhaps that has something to do with it. I fixed it using Solid Inspector2. I also cleaned up a bunch of unneeded edges Dust Hood.skp (187.6 KB)
SketchUp didn’t call them both solid, though. After cleaning up the unneeded triangulation Solid Inspector 2 shows an internal face. After fixing that, SketchUp called it Solid.
