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

A weldment starts from a skeleton sketch (2D or 3D): each segment becomes the centerline of a profile.

2

The Structural Member sweeps a profile along the selected segments; one member can group several segments.

3

Profiles are library files: standards, types and sizes are stored in folders, and you can create your own.

4

The whole structure remains a single multibody part: each profile is a body.

Tip

Build the skeleton sketch with global driving dimensions (length, width, height): the whole frame resizes when you change three values.

3. Do the exercise

Create a workbench in 40 × 40 × 3 square tube:

  • 1,200 × 600 mm top frame
  • four 850 mm legs
  • a lower crossbar on both long sides
✓To check: Change the top length in the sketch: all profiles must follow.
