The control object is in an unexpected viewport when using _CageEdit in the UV Editor.
Also it is very small, in my first attempts I didn’t see it at all.

In that case, Cplane is the right cage orientation to choose
Aha, ok, makes sense of course.
Thanks for the hint.
ObjectPlane = Cplane, correct?
Yes, it´s the CPlane of which you see the grid when working in the UVEditor
