Fabrication drawing sets

Two complete fabrication and assembly drawing sets drawn in Inventor: a belt tensioner with non-standard internal geometry, and a ball towing coupling detailed enough to be fabricated and assembled without further information.

What I did

Modelled and assembled both mechanisms, then drew orthographic and section views with fits and surface finishes, and, on each assembly sheet, an exploded isometric tied to a parts list.
Gave the coupling a detail sheet for each fabricated part and per-component masses in its parts list, and inserted its washer and nut from the ISO metric parts catalogue rather than drawing standard parts.
