I used Boolean difference but after 20 minutes of running, the program crashes. I think maybe it's too complex for the program ?! I'd be glad to hear your ideas on how to do this.</P><P>&nbsp;</P><P>Thanks</P> Thu, 07 May 2020 09:19:45 GMT https://forums.autodesk.com/t5/meshmixer-forum/boolean-difference/m-p/9498498#M2568 Anonymous 2020-05-07T09:19:45Z https://forums.autodesk.com/t5/meshmixer-forum/boolean-difference/m-p/9502890#M2569 <P>Boolean operations often fail on scans.
