Martin, probably You haven´t understood the point - sent models are based on proper drawing (point 1.); there are no "strange objects" in there, unless "outline in" walls.. (Anyway I did try to rotate the walls in th2 as well with no change, - but of course I respect this topic) I noticed destroyed models in Meshlab (Paraview is maybe the source of troubles) just when fixed points were present in source.
