Some users like to use third-party software for cleaning and repairing meshes, for example
FreeCAD has some capabilities for mesh operation in mesh workbench and OpenSCAD workbench (some operations need OpenSCAD to be installed and configured in the FreeCAD-preferences). For a successful conversion from mesh to solid we need to make sure that the mesh is “water-tight” (has no holes) or doesn’t have any other errors.įreeCAD’s aim is not to be a good mesh modeler, it is designed to be a solid modeler. But our goal is to have a solid which can be measured and changed (adding pads/pockets.
