Translations:Manual:Traditional modeling, the CSG way/3/en

As we saw earlier in this manual, FreeCAD can handle many types of geometry, but the preferred and most useful type for the kind of 3D objects that we want to design with FreeCAD, that is, real-world objects, is, without a doubt, solid, BREP geometry, that is mainly handled by the Part Workbench. Unlike polygon meshes, which are made only of points and triangles, BREP objects have their faces defined by mathematical curves, which permits abolute precision, no matter the scale.
