Geometry
Shafts, sleeves, bushings, spacers, fittings, knobs, and threaded hardware can combine external and internal turned features.
Drawing control
Thread standard, fits, concentric features, edge breaks, and inspection datums should be visible on the 2D drawing.
Production fit
Material form, part length, diameter range, secondary features, quantity, and finish all influence the process route.

Buyer Questions
Why include a 2D drawing with the model?
The drawing carries thread, fit, surface, and inspection notes that a model alone may not communicate.
Can milled features be added?
Yes, depending on geometry. Flats, cross holes, slots, and wrench features should be included in the files for review.
