Good morning all,

I always seem to have issues when trying to convert an irregular curve into sheet metal.  Please see the attached file and the below snip.  Its just a basic rectangle with a few bumps on the brake.  I will give a template to the shop guy but would like to get a nice flat pattern on a sketch that he can use for reference.  Its basically a parabolic curve sketch.  I tried using sheet metal boss / base flange but that won't work.  I can get the curve to a thin feature extrude but then can't convert to sheet metal.  Any suggestions? I also tried "insert bends" with no luck. Must be something trivial I'm overlooking. Thanks in advance.

and when picking one of the bend lines:
