AW: boolean operations with .stl

We are also using magics (sligthly modified to match our needs). I need the boolean operations quite often and they perform without
any problems. We are designing lingual (invisible) braces. The brackets are build on a MM2 and afterwards cast in dental gold. On
our homepage you will find a gallery, which shows also the design process in magics. For scanning the
arches we use a very reliable GOM-Scanner.

Best regards,
