Translations:Import from STL or OBJ/2/en

In this tutorial we will cover how to import STL/OBJ files in FreeCAD. Since the mesh-format STL/OBJ is dimensionless, FreeCAD will assume on import that the units used in the model are mm. 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.
