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.
