Splitting stl files Tagged: cutting, meshmixer Author Posts March 2, 2019 at 7:18 pm #139018 geoffrey.hollandParticipant Hi All, What software do people use (MAC) to split stl files? I know that small files are provided but sometimes I want my own cuts. Any input would be great. Thanks, March 4, 2019 at 12:18 pm #139257 MattParticipant I recommend Meshmixer for cutting. This is what i usually use for cutting things as a one off: Plane cut, export stl, undo, select other side of plane cut and then export stl.
