Miter Flange help

I just recently started using the Sheet Metal features in SolidWorks, and I can't exactly figure how to add miter flanges to the opening of this triangular enclosure (triangle.jpg).

When I use the feature, I sketch a line profile in the direction I want the flange to go as shown in the picture, but when I select another edge, the flange isn't generated for the other edges.

I want it to end up like how the picture is shown in triangle2.jpg. At the moment I'm simply using 4 edge flanges and editting the geometry so each of the flanges curve in at a 45 degree angle.

My guess is that it is struggling with the fact that the flange is a 90 degree bend on the side but not on the top due to the triange nature of the part. No matter what, you would need to add an edge flange to the bottom anyway because the miter flange can only go around bends (can't jump gaps). I think the edge bend is the only way to go for this part. Just relate the sketch of subsequent flanges back to the first and you will have the same functionality (almost) as the miter flange. Update first one, the rest update.

Thanks Dustin, I'm currently just sticking with the edge flange and relating the sketches and it's enough for now. It's unfortunate that the miter flange feature can't be used to create this sort of geometry.

Just a thought - how do you plan to form that part? Would it make more sense to make it in two pieces that are welded together?

I plan to just create it out of one sheet metal part. I would have considered welding two parts together if aesthetics was an important factor in this part.

If you pan to make it out of one piece, how will you form it? It seems to me that it will be quite difficult to form the last bend.
