I was working on a project with a series of walls off set 3/4". after laying out the building and looking at it in 3d modes every thing was as it should appear. After adding site elements (sidewalks and mesh) I reviewed the project again in 3d and the walls appear skewed when shown in perspective but not in isometic, sections or elevations. By the way at one point archicad crashed during the rendering process. I can attach the pln. if that would help.
