Translations:Creating a simple part with Draft and Part WB/58/en

Sooner or later when working with 3D parametric CAD you will come across a broken model, either one you have made yourself, or a model that you have imported. A broken model can work for its purpose, but more often than not, there are subsequent operations that simply will not work. To repair a broken model one has to know what to repair, this is where the built-in quality check tools in FreeCAD come in.
