I have a part that we get in with some angles ground on it.  We then take this part and form it to have corrugations.

I cannot figure out a better way to create the final product than extrude cutting the area that will be formed and lofting in a new area.  Then I must sweep the angles onto the formed area.

Is there a better/different way to generate this part?

(please note: I created this part as a sample, I realize the swept cuts are not correct.  I just wanted to create this sample part quickly.)
