I haven't used Flex very much and am struggling to get this to do what I want.
I attached a STEP file of a model. I want to flex the area between the two sets of vertical marks and rotate it by some angle - say 15 degrees. I want the area between the two marks rotated about the X (and the center of the part would be the center of rotation) so when it's done from the side it would look something like this:
So I'd have two straight areas on the edges and then a middle section which is rotated.
