When I had to rotate a plane, I used to be able to point to another plane with the rotator tool, and fix the rotator orientation to be the same of that other plane. If I’m not wrong I just had to press Alt (or a similar key) when in that other plane and then I could come to the shape I wanted to rotate in that same direction. But now (maybe since Sketchup 2017?), I can’t.
Is there anything I’m missing?
This is the plane I want to rotate as if it was an unfolded box. I’m trying to make sketchup infer the directiong of the transversal plane (the thin one facing us) of the white figure at the top-left of the pic:
but I can’t make the rotator change from that blue horizontal plane…
