How can I put a hem bend along the edge of a curved surface?

Helping a SolidWorks user.

"I am designing a sheet metal cover that has a constant curve from left to right but around all four edges I need to have a hem bend.

Is this possible in SW 2011?"

easiest (in NX) way to do that is to give it thickness and bland edges of solid then extract surfaces...
i can't help more as I do not use SW :(

I am a press brake setter. to do this with real material we hem the the flat sheet then roll with equal guage sheet to get a constant curve. I am new to solidworks so I don't know if you could find a way of incorporating this into a part or assembly. hope it helps

On the outside edges you can use an edge flange and sketched bends. No idea how to do it on the curved edges or if it is even possible. You may be able to create a forming tool for the curved edges.

i think you could make a 3d Sketch then convert entities (the border loop) then on a planar sketch you make the hem profile, then sweep it across the path it should work..

As J E Paz noted, you can sweep the hem profile which will give you a part of the desired design, however SW will not be able to convert it to a sheet metal part and flatten it. Best I can tell, Dassault feels that anything made of a thin, bent piece of metal MUST have at least one planer surface.

I'm afraid I don't know Solidworks, but Inventor permits us to sketch the flange cross-section at the edge, and then have it chase the edge using a few criteria and options in the sweep tool.

How complex is the curve? Probably this part can help... you can check the steps I took for it, propbably works too for solidworks. The flat pattern works!
