Perspective window and forced planar

I can do this in 7 but 8 projects everything on XY-plane. It is infuriating.
In case image is not loaded (Can’t see it while typing this): Draw two rectangles, move other by Z-axis, try to make a new face connectin with “surface from 3 or 4 corner points” related corners of aforementioned rectangles, all 8 does is to draw a lousy projection of the intended new surface to XZ-plane.

Ar you sure you don’t have “Project” checked in the Osnap panel?

Yes I am.

A good point, have to check it later. I thought about planar. Thanks, I’ll try that later.

Hmm, no issue here…
