I need to create a surface that follows the curves shown. The edges are invariant. The sides of the surface need to be straight at the left end of the bottom curve. This meets a straight “tail” shown by the top curve. The sides need to be straight at the right end and most of the way to the kink in the top link. In the zone from the upward curve to the a little past the kink, I can be flexible.
The kink causes all kinds of problems. I drew lines through reference points and extended them the same height. Then I created a curve at the top and bottom through the ends.
I then sweep those lines and trim to the original lines:
This is mostly correct (the killer 5%) but I would like to eliminate the dent under the kink (that naturally occurs because of the line there. Thus, in this sone I would like to have some set of curves that would cause this area to pop out rather than pop in.
I have tried creating waterlines, trimming, around the area, then inserting a convex curve. The problem I get then is the new frames create accordion pleats when swept.

I was wondering if there is some simple way to pop this dent out.
