this is so strange...I delete the crop, close and reopen and the crop returns. I delete the crop, draw a new one, close and reopen, it is offset like the previous one. It is seemingly impossible to fix a DTM if its moved, is this true? I never knew the crop would be so significant.
I will have to go back to the original DTM in another drawing and start form there .
This sure is frustrating, even the original DTM's crop is slightly offset, but not a big problem, I guess I may have accidentally moved the DTM.
