Shape rotation bug

[baltic]

If you say so, it's a bug in the model, not in the modeling software. I still can think of cases were such modeling is sensible as an intermediate state, and thus should not be forbidden. If you would like an additional warning, it's a feature request.

Model is pretty valid. And I've never told you it should be forbidden. It just should not give incorrect results in rotation. That's what the subject is all about. And incorrect results in rotation is an obvious bug.
You really seem to have troubles comprehending the issue from the very beginning. Your advises were irrelevant and not helpful. But anyway, If you still don't get it, you probably never will. I'm out of this conversation.
