lofted flange converge - sheet metal

Can someone tell me what the sheet metal "converge" does in the lofted flange command?
Reason I ask is b/c I'm trying to create a simple press-broke corner for a transitional hopper, but inventor keeps messing it up.

The attached pic shows what inventor does to make this part.

in reality there is no intermediate wedge at the convergence point.

in the shop, we press brake all the way around the 2 defining edge curves, based on the brake lines we draw from end to end as separaged by equal distances (like many pie shapes) all along the 2 edge curves

this inventor model is garbage, and never would happen in the real world.

how do i eliminate this 'stupid' wedge?

i tried using "converge", but nothing in the help file explains EXACTLY WHAT IT DOES.

also, if i try switching from "converge" to non-converge (and vice versa), the program crashes EVERY TIME.

that tells me there's a BUG in this software that needs fixing.

some help would be appreciated from someone who knows.

thanks ... chirs

Could you attach the sheet metal for more details?

River,

Sorry, I deleted that part.

No worries, since I figured out how to do it another way.

Interesting note:

Today I tried to create the part using all 3 "Facet Control" methods and it worked just fine.

What I don't udnerstaned is this:
1. Why does the program crashes every time I try to switch between "Facet Control" methods after a loft has already been created? and

2. Why does the program not work like I shoed in thie pic, and then some time later (after a shut-down over night & a reboot) it works just fine?

Hello,

I have recreated the lofted flange from scratch based on the image you attached, and there is no issue seen. If possible, could you let me know how to create the sketch profile for this? And I find the sketch profile for lofted flange is derived from one base.

Thanks,
River
