Anyone else able to reproduce this?
I've tried it on a couple different machines, and in different files, including the Graphisoft 23 template file, so I don't think it is a settings issue.
This is a big deal! The model view does not match the plan view for things like ceilings and floor tile patterns, where alignments are sometimes critical. I don't want to be sitting in front of the screen with my boss trying to explain that the ceiling grid is one way in plan but different in 3D because our software used to work but now it doesn't.
