Hi I'm having some difficulty introducing  gussets to a part (see attached image), After a lot of playing around with forming tools and the gusset feature I managed to add a gusset to a right angle. This was done with the gusset tool as there seemed to be large limitations as to what can be done with a form tool (the part needed to be quite thin) I was wondering if anyone had ideas of how to introduce a gusset for a bend that is not 90, for example I want to gusset the attached part on an angle of around 20 degrees. I did manage to introduce a gusset of some description one of the bends but it turned out cubic not cylindrical, I need a round gusset across the bend, any help would be awesome.

Cheers.
