Lofted Flange extra bend...Why??

[Anonymous]

I have tried to do a lofted flange. It works, but there is an extra bend that I don't understand why it is there. The bends, I would assume, should be symmetrical but they are not. I have attached the part. Any help would be greatly appreciated.

Here's another method. Perhaps not the best, but it works.. I suggest keeping your sketches simpler. You have too many dimensions.

Edit: the forum is acting up and not letting me attach my part. I'll try again latter.

Do you really need this to be lofted? It's a sheetmetal part after all.
That aside, I don't know why the loft is mapping the sketches properly but if you add a .25 radius to the four bottom corners of the sketches, it will give the part you're looking for.

(S)He probably wants a loft so that she can get a faceted radius that can be produced with a press brake. I often do the same thing. It would be slick if Contour flange could give us facets but...

You might take another look at the OP's file. His sketches were just a bit different.
