So I'm not so sure the correct description is "edge flange for internal edge", but I'm hoping someone might be able to shed some light on something for me!

I am modelling a part that may or may not NEED to be a sheet metal part, but I dont see why It cant be modeled using sheet metal. That said, I'll admit to not having used sheet metal all that much and so I wanted to model it using sheet metal as a bit of a learning exercise.

Below is a screen shot of what I am trying to do, the base flange is a piece of plate rolled to a radius. I then want to make what would effectively be an edge flange from an edge of the cut out region to for a tab, bend out from the original plate. So far, I have tried:

- edge flange (I assume can only be used on external (straight) edges)

- sketched bend, which sort of worked by adding a base flange to the 'bend edge' then beding that. This however, results in 2 bodies...

How do you do this? Do I need to use a form tool? Can a swept flange do the job?

Normally I would say that there isnt too much I cant do/figure out in SWrks, but sheet metal is a little alien to me and this one has me stumped. I hope its an easy solution that makes me look stuipid!
