And btw, there is the class "TransformPointsDialog" that is not used in AoI Core code. Shouldn't it be marked deprecated?

Yes. individual functions of Transform Object work correctly. That was never the problem. The original issue is about performing moves and rotation _in one step_. The expectation would be that...

Just as a side track, I had a look at the coordinate angles thing. Where it goes wrong is in the `findRotationAngles()` of CoordinateSystem, in the first `if`-block, starting on...
