Swept Flanges 
You can create compound bends in sheet metal parts using the Swept Flange tool.
The Swept Flange tool is similar to the Sweep tool; you need a profile and path to create the flange. To create a swept flange, you need an open sketch as the profile, and an open profile path or a series of existing edges in a sheet metal part.

Any cuts, holes, chamfers, or fillets on the bend region of the swept flange do not appear in the flat pattern.
- Open install_dir\samples\whatsnew\sheetmetal\swept_bend.sldprt.
A part with two sketches opens.
