Did Rob Flange the Flange?
In the version-21 drawing file, the Extrude is 1.163, and the first flange is 1.669.
Then it appears-- from the images I've been seeing in this thread-- that the first Flange has the little, second, Flange.
Perhaps flanging the flange is an issue when trying to UnBend.
In version-21, I went the other way, and successfully UnBent:
>Via/In the provided file, via Selection Info Part Tree, I copied the initial Extrude.
>I pasted that into Modelspace.
>I made the Y size of the Extrude's associated Polyline 1.669.
>I then did the first Flange, all the values being the same as the original file, except the Height being 1.163.
>I did the second Flange-- on the initial Extrude Part, now having a 1.163 Flange, same values as the original file.
>Successfully UnBent from the "Back". That result is the Blue Part, in the attached file.
I would think that it would also be good practice to make the Neutral Depths the same, when working with the same sheet metal object.
I can see how having them varied, as in the original file, can cause issues. The Flanges' Neutral Depths are different, in the original file (filtered for V21) provided to me.
Plus, isn't that how it'd be done in the real-World anyway.
Just makes more sense and makes it all easier to work with if all the Bends and Flanges have the same Neutral Depth.
