As such, it’s mainly an option for polishing up a technical object or part.įreeCAD’s most interesting aspect in the context of STL files is a comprehensive mesh repair tool to prepare a mesh for 3D printing.īased on a selection of user-defined options, including orientation, duplicate points, degenerated faces, and more, the tool analyzes a mesh for any discrepancies and then goes about repairing them with no more than a few clicks. You can add basic holes and extrusions, but more artistic modeling is more or less out of the question. However, the editing and sculpting options are reasonably limited. It allows you to import an STL file, extract a mesh from the model, create a solid equivalent shape, and refine it ready for editing. Operating System Compatibility: Windows, macOS, Linuxįree to use and open-source, FreeCAD is a computer-aided design program mainly for the creation of mechanical and technical drawings and models.
