Frank I have a question that hopefully you can answer. We download and convert all our cases to .stl files and send them to our 3shape to print models and design the cases. The problem is that the doctor marked margins do not export with the files. So we end up having to guess where the margins are and of course you know how that usually ends up. Do you know of a process to get this to export? If not who would I need to call? Thanks for any info you can give!
