I end up having to tweak .STL files all the time and mostly end up using meshmixer. Meshmixer is great for filling holes and organic free hand changes but doesn’t do accurate geometric changes such as fillets, chamfers, and the like. I use solidworks all the time but it also doesn’t handle large stl files. Is there anything out there free or otherwise that edits .STL files geometrically where you don’t have access to the original model data? http://ift.tt/29Q32pc
