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.

Sketching with a Grid SystemVideo 1▶Sketching with a Grid SystemUse a reference grid as the skeleton of a structure.↗ Introduction to Structure SystemVideo 2▶Introduction to Structure SystemCreate and edit members with different profiles in a single feature.↗ Structure System: Trim MembersVideo 3▶Structure System: Trim MembersHandle corners and lengths with corner management.↗ Structure System: Cut ListVideo 4▶Structure System: Cut ListOrganize bodies and their properties in the cut list.↗

2. Key takeaways

1

The grid is reference geometry: columns and beams rest on its lines and levels.

2

Structure System creates members with different profiles in a single feature, even without a complete sketch.

3

Corner management handles all joints in one place, corner by corner.

4

For a small frame, the standard Structural Member is still simpler; Structure System has the edge on large structures.

Tip

For a multi-level structure, create the grid first using the dimensions from the layout plan: changes to the grid then carry over to the whole structure.

3. Do the exercise

Model a small mezzanine:

  • grid of 3 × 2 bays of 3 m, height 2.5 m
  • HEA 140 columns, IPE 160 beams
  • handle the joints with corner management
✓To check: The cut list groups identical columns and beams with the correct quantities.
