Add an option to detail views that, upon selection of a threaded feature (parts AND assemblies, please), shows the actual geometry of the screw thread (including correct direction of asymmetrical thread as shown in the attachment). The detail *must* be keyed to the thread specified in the model and would change if the model thread changed. The thread geometry detail would also be dimensionable as shown. In a perfect world, we would be able to extract the correct thread dimensions from the detail (or main view) such as the major, pitch, minor and their correct tolerances.
There should also be an easy way for users (the folks paying Autodesk) to add threads (including modified or custom ones) to this system that would also be recognized in the same way.
