Sheet Metal - Spot weld help

andrew_banham

Hi

I'm teaching my students how to use the Sheet Metal features of Onshape and they are going great.... but ...

We are stuck trying to produce simple overlapping corner joints that would be spot welded or riveted etc.

(see: a simple SM box picture found on the internet to help explain)

Check out this doc. I have added some offset to get the overlapping tabs working.

Yep, this is typical of most CAD packages. Having sheet metal surfaces touch each other tends to throw things out of wack. If you have a joint that is supposed to be riveted or welded, leaving some small offset (even .0001in) between the surfaces helps keep the CAD from complaining.
