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.
Video 1▶Sheet Metal CutsRemove material normal to the sheet, including across bends.↗
Video 2▶Closed CornersExtend two adjacent flanges to close the corner, with the gap or overlap you want.↗
Video 3▶Forming Tools for Sheet Metal PartsAdd embosses, louvers and ribs from the library, and create your own tools.↗
2. Key takeaways
For a clean cut, select the Normal cut option: the cut stays perpendicular to the material, even on a curved face.
To cut across a bend, Unfold, cut flat, then Fold: the cut follows the bend.
The Closed Corner extends the flanges to reduce the gap between two adjacent flanges: set the gap according to the process (welding, bending).
Forming tools are dragged from the Design Library; you choose whether they appear in the flat pattern.
Tip
Create your own forming tools for your shop's standard shapes (embosses, cable grommets): you can then place them with a single drag and drop.
3. Do the exercise
On the cover from lesson 2:
- make a 30 × 10 mm slot cut straddling a bend
- close the two front corners with a 0.5 mm gap
- add a louver on the top face
