I have two base flanges on separate planes. It seems that the best way to connect these two, to form a single sheet metal body, is to use an edge flange. However, when I create the edge flange, I cannot get the edge flange to expand on one end to match up to the larger of the two base flanges. Even when I edit the sketch for the edge flange, it just goes back to the original sketch when I exit. I would like to avoid this part making a T.

Any ideas?
