Alright, back at it again... So we received a case via Trios to do a digital diagnostic waxup, but we're running into a problem and I'm not sure how to address it. We designed the diagnostic using "temporary pontic on prepared model," finished it all up, copy and appended the design for reuse... but now the unaltered preparation model is showing through our design. I'm not sure how to rectify this because I don't know of a way to get an stl and trim down the preparation arch (again) in a different software, say Meshmixer... but I'm not sure how to get it to append a model with the altered preparation arch, either. The fact that this is a digital model instead of a scan is kinda tying my hands. Has anyone ran into this issue before and know a solution?
