Rebuild Mesh window not showing up

No matter what I do, I can have ‘rebuild mesh’ window open up. Rebooted the computer didn’t help either. I use dual monitors, so I also tried to activate only one monitor. In Command line, I see that “_RebuildMesh,” but I can’t edit anything because there’s no editing window showing up. Any ideas?

Hello - RebuildMesh does not have a dialog, if that is what you are expecting. It just ‘does it’ See Help on this command, it is not really related to the Rebuild command in any way.


Maybe you mean to use MeshRepair?

I probably need sleep. What I was trying to do was, ‘reduce mesh.’

It drove me crazy that I couldn’t simplify unnecessarily heavy Sketchup objects. Thanks for your replies.
