Which visual differences are occluded depending on the design and CAD software parameters? If [FreeCAD] files are text-diffable, is there a way to topologically sort (with secondary insertion order) before git committing with e.g. precommit? python has a sort_keys parameter for serialization, in order to alphabetically sort sibling nodes in nested datastructures; which makes it easier to diff json documents that have different key orderings but otherwise equal content.
