Hey all, I have a persistent and super annoying problem that neither 3shape nor itero can solve. Whenever I have preps opposing each other, one arch will have the annotations and margins on the opposite side of the arch and all buggered up. It happens everytime. I can't seem to ignore the scanning annotations, and if I try to do any tricks with importing scans and splitting the file up my model builder won't let me (I have 3rd party, not stl.) Any ideas? This must happen to everyone all the time!
