Turned parts
Shafts, pins and pulleys come from one revolved profile.
VIZON CAD covers the features most single mechanical parts need: extrudes, revolves, holes, fillets, chamfers, shells and patterns, all editable and exportable as STEP.

Shafts, pins and pulleys come from one revolved profile.
One hole plus a circular pattern gives evenly spaced holes you can recount any time.
Linear patterns repeat fins, ribs and slots at a set pitch.
Extruded profiles with slots, holes and inside fillets.
Use standard clearance and tap-drill sizes for metric screws.
Export STEP to send to machine shops or open in other CAD tools.
