Hello Everyone, I am making this 3d Model out of Sheet metal but I am having a problem finishing it. On the very bottom of the part, I want the red and the green surface to be parallel to the Y-axis on both sides. The sketch "Desired Geometry" shows what I am trying to make. I tried using corner seam but it gives me error. The distance between the two red surface can vary. Any suggessions on how this shape can be acheived which will give me a correct flat pattern too.
