1 – Why use Sheetmetal Design?



- Design simpler than Partdesign for the sheet metal parts

- Modify easily all the parameters of the sheet metal fabrication

(thickness, general radius, cutting)

- Sheetmetal design parts are closer to the real part

- Allows generation of the unfolded part and the dxf file for water jet or

laser cutting

- Hybrid design with Sheetmetal Design and Partdesign

2 – Sheetmetal design, for which

type of parts?



1st case – Bent + Welded Box

Different automatic cutting

Generation of different geometries for the angles


type of parts?




ADVANTAGE : Input parameters are

easily modifiable


type of parts?




Simple modification of the thickness and internal radius

2nd case – RF contact

With Part Design

Need to recognize the part as a sheet

metal part to have the unfolded part


type of parts?



2nd case – RF contact

With Sheetmetal design

1/ 2 / 3 /

ADVANTAGES :

Simple to design and the dxf file of

the raw material is easy to extract



Impossible configuration

Difficult to identify with a

classic Part Design construction

The system refuses to compute a

hole pattern because of the overlapping


type of parts?

3rd case – Riveted Bent Corner Bracket



ADVANTAGES :

- Helps you to improve design

- Hybrid design possibility

- Advanced shapes easy to design

Check the raw material on the unfolded part :SHEET - Cu-OFE - EDMS 790780 thickness 2mm

=> 1000x2000 => too small, add sheets

by welding or mechanical tightening

4th case – Thermal shield

ADVANTAGES :

- The Recognize function enables

transformation of a Part Design model into a

Sheetmetal model

- Watch out where you apply it !

- Overall dimensions of the raw plate

immediately accessible

Holes disappeared, because they

have been done with Partdesign

4 – Conclusion

If you are no sure or if you have some questions about your design

and his fabrication:

Don’t hesitate to ask to the workshop

The preparation service from the section FS will be enjoy to help you

THANKS YOU FOR YOUR ATTENTION !!!
