FreeCAD is a parametric 3D modeler, this allows you to change any placement or dimension and the model will update accordingly. In general this works, but it is possible to break a model when edited – for example when a fillet is based on an edge that no longer exists due to editing. When a model breaks during editing, it is referred to as TNP, Topological Naming Problem.
