After running Mazatrol for a few decades which is a basic version of what a CAD/CAM program such as Fusion 360 is doing. I have found that perhaps some of this has been overlooked in development. Perhaps a simple Line Left, Right and Center could be considered where complicated toolpaths aren't necessary. Also I have come across the difficulty as others have stated in the use of American NPT threading do to there only being Metric available. We mostly use threadmilling and would make life easier if they were available.
