Hi Tarquin Thanks a lot for your advices! It was not a wrong station point but missing ones. I did not have all stations within the drawing but only some. And therefore not all surveys did have stations marked in the drawing. With "debug on" the distortion was very obvious. Now that I have inserted all stations ... tadaaa ... everything shows up as expected. THANK YOU! regards, Torsten
