Sheetmetal bending help

[ctopher]

I have a part that has several 'donuts' linked with tabs.
The part is .002 thk. How can I bend the part so that the tabs are bent with the 'donuts' stacked alternating on top of each other at certain distance between them?
thanks you

Try modeling the part in its formed state, and then unfold it.

Good and evil: wrap them up and disguise it as people.

That will work provided that the bends are straight... SW sheetmetal does not support bends around a curve..

Excuse the crude ASCII art...

I would start off sketching like above, then cut-away the material required to make your connected donuts, then Insert>Bends.

thanks, the shape I am looking for is the 'donuts' stacked vertically, .010 between them with the tabs curving alternately on each side 180 deg apart.

I GOT IT!
After meswsing with it for a while....
I created a solid of one donut with parts of tabs 180 deg apart, then added a hem to one of them. Then created a second solid like the first one based off the hem surface. Then a third hem off the other tab and so on...
When I click on unfold..WOW!
thanks everyone.

You could model a strip of the profile, add the sheetmetal bends, and then cut it to shape.

If anyone wants to see the part on how I did it, let me know and I can e-mail it to you.
