Inventor · Section views & hatching · Fits & tolerances · Exploded assemblies

What I did

  • Modelled all parts and assembled to produce four drawing sheets with orthogonal and section views to communicate internal geometry, fits and surface finishes. Exploded isometric tied to a ten-item detailed parts list

Drawing
