Detect edges of self-touching solids about solid-inspector

I agree that it's maybe rather something that needs improvement in SketchUp's solid checker.

A user sees in Entity Info not a solid (according to SketchUp's definition), and wants to find out why SketchUp doesn't detect it.
But if this extension's goal is focussed on real solidness/printability (and not debugging whether something is solid to SketchUp's definition), then it's perfectly comprehensible. I just wanted to knwo your opinion.

SketchUp doesn't recognize this as a manifold because not all edges connects to two faces - which is a very naive test that doesn't account for this edge case. It is however a valid solid. The model should be printable.

I'm closing this as an invalid issue as the goal of Solid Inspector is not to match what SketchUp says is a solid, but provide a better analysis.

If you think that this edge case is a problem that should be marked as an error then please object and I'll certainly listen.
