Selecting your mesh object in the tree view.Harmonizing normals of a mesh object can be done by If errors had been detected the corresponding check-boxes will be ticked and you will be able to select Repair.The texts beside the tick boxes will change to reflect results of the different tests.

In this tutorial we will use the mesh workbench within FreeCAD to clean/repair/verify the mesh of our sample file.

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. Save your file with File → Save to get a FreeCAD-File containing a mesh objectįor importing a STL or OBJ file into FreeCAD, create a new FreeCAD document und choose File → Import from the top menu.Ĭleaning and repairing the STL/OBJ-File for preparing importīasically, FreeCAD would import any STL/OBJ-File.Insert a torus by clicking on Meshes → Regular solid., choosing settings like:.If this is not the case you have to scale your model either in the application it was created with (before exporting it) or you have to scale your model in FreeCAD after import and conversion to a solid.įor this tutorial you can use your own STL file or create a demo file by doing this: Since the mesh-format STL/OBJ is dimensionless, FreeCAD will assume on import that the units used in the model are mm.

The file format is open and has been adopted by other 3D graphics application vendors.Īn STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. obj) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. Binary files are more common since they are more compact. The STL format specifies both ASCII and binary representations. STL files describe only the surface geometry of a three-dimensional object without representing color, texture, or other common CAD model attributes. It is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing. Many other software packages support this file format. STL is a file format native to the stereolithography CAD software created by 3D Systems.
