Trapezoidal threads are created with the wrong angle (currently 60° but should be 30°) which makes them unusable in real life. Before the latest update it was possible to change this in the threaddata folder and also create custom threads that aren't available (even multistart threads could be made with a copy and rotation) but since the latest update this folder has disappeared along with the custom threads I had made. It would be great if this could be restored to allow customising or even better allow custom threads to be input directly in fusion rather than having to edit the xml files.
