3D sketch to sheetmetal

Is there a convienet work around to turn a 3D sketch into a sheetmetal part? I am attempting to create a fabricated tube face where the face is at an angle to the top and bottom other than 90 degrees and the curvature of the face is constrained by elipses rather than radisus. I can lay out the curvature by creating a 3D sketch but converting to a sheetmetal part is not working. I have also attempted to create a surface and turn that to sheet metal with no results.

Thank you

Jim
