How can one create a bend with a Punch Rib feature in SW sheetmetal?

Greetings:

Does anyone have some experience with SW sheetmetal? If so how do you
create a bend feature with a punch rib as shown
http://pwanghk.sphosting.com/SW/ClipWithPunchRib.jpg? I try to create
a punch first then bend, vice versa and both failed. The clip should
look like this http://pwanghk.sphosting.com/SW/ClipWithoutPunchRib.jpg
with the punch rib on both side. Any suggestion to create this would
be greatly appreciated.

Please use copy and paste in case the link doesn't work properly.

 

To truly flatten that part is a limitation. You could "fake it" by just
builidng the features into the model, and when flattened just suppress the
features you used to make it "look right". If you really need it flattened i
believe there is at least one add-in program that can handle deformation.

Tood: Thank you for your information.

Could you please enlighten me, what add-in program that can handle deformation?

Thanks for your time and help.

Yeah, you can kind of do that. It's not as nice as you might want it to
be. Here is an example:

http://www.frontiernet.net/~mlombard/

Follow the SWParts link, and down at the bottom is the "form across
bends" image. It works backwards from how you want to do it, you are
trying to form the rib, then bend the part, but the way you have to create
it is to bend the part, then put the rib over the bends. You could form it
flat, then use configs and suppress the feature and do it the way shown in
the sample if you have to show it in-process.

Anyway, if you don't get it or can't figure it out from the example, post
again, and I'll try to explain in more detail.
