1. Watch the videos

Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.

2. Key takeaways

1

Blind sets a depth; Through All and Up To Next follow the geometry if the thickness changes.

2

Choose the end condition based on intent: a through hole must stay a through hole when the plate gets thicker.

3

A revolve requires a profile on one side of the axis only; a construction line can serve as the axis.

4

A reference plane is useful when no planar face exists where you need to sketch.

Tip

For a symmetrical part, extrude with Mid Plane from an origin plane: symmetry is guaranteed every time the thickness changes.

3. Do the exercise

Model a stepped shaft and its flange:

  • create the shaft by revolving a profile with three diameters
  • create a plane offset 20 mm from an end face
  • add a Through All cut on the flange
✓To check: Lengthen the flange by 10 mm: the cut stays through without any intervention.
