Hello... I have made a digitalization of the hand of a boy who needs an orthosis to help him to move the hand. I have worked the file with Meshmixer and Netfabb and now need to import it to SolidWorks to draw the orthosis. What's happened is that the file is very heavy and SW crash a lot of times.

I want to ask help for the best way to work with this model and how to import it to SW.

Should I use another kind of software to make the orthosis?

Thnaks in advance for your help.
