development sheet frame

[GiGa]

I have to get the development of a folded sheet frame.
I've gotten into the development of that in the attached image without great problems but to build it I had to use a definitely incorrect method.
In practice it is a simple composition of extrusions that, once exported as individual elements, I transformed into sheet metal obtaining its development.
the problem is that the sheets so developed have the edges cut (in thickness) with a certain angle (due to the coincidence between the elements).
the customer, rightly, would like to have the shape with the orthogonal cut to the surface. The problem is I don't go out...
unable to start from an initial face, I can not do "flange" or "flange contour", also because, when I could build the frame this would be a manybody, therefore incompatible with the sheet environment.
However, in order to shape the four corner edges of the frame, I should have the two adjacent, otherwise they would be simple rectangular flanges. . .
How can I do that?

I hope I've explained decently. . .

Does that happen to you?
in practice to solve, with solidworks, it is enough to enable the check
on "normal cut" and the sw performs cuts in an orthogonal way to the thickness
of sheet metal.
I'm sorry I couldn't help you. I don't have inventor. Maybe there's a similar option.
Hi.

I also have the same problem.... .

I usually sketch the profile, then I do a super extrusion of the length I need, then I perform the cut at 45° at one end, I make the fittings ( paying attention to the internal or external fold radius), at the end I thicken and as a value do "thick".

quoting in full.
when I have to do something in sheet metal with the parts that intersect, I make a part of only surfaces, then comes into multiple sheet files and I thicken an element for file.comodo also because if I have to change something, it varies in the father file and the rest fits.
sure that if they had extended the multibody to the sheet module...

Thank you for your help. actually the method of surfaces is nothing bad.. .
As soon as I have a little time, I have to go deeper. . .
possible that it is so "out of the ordinary" having to make a sheet bent and shaped with the perpendicular cut to the surface?
It seems strange to me that there is no command/option somewhere to do something like this in the sheet metal environment. . .

sure that if they had extended the multibody to the sheet module....

It would be a great step forward.. .
It seems to me that not even in 2013 you talk about it... We look forward to 2014.. .


ps: in the end the customer explained how to prepare the developments of the plates... I hope only that I do not call back when in the workshop will find mm of material in less or the corners that do not coincide... Fortunately they are few pieces.. .
