folded sheet development with error

[mir]

Hello, guys.
I did this object in cad and then I imported it into inventor for development on the floor but nothing ... it gives me error and does not develop it ... but it is very simple.

Where can I go wrong?

Thank you.

I suppose you drew the profiles with the thicknesses on two different planes and then you made a loft between the two sketches.
You find yourself with a thickness of 1,973 mm and rays that are not circular rays but elliptic rays.
That's why she doesn't develop it.
a construction so built to the cad (I suppose autocad...) only works if the fold you go to make has a constant profile and has the perpendicular bases to the extrusion axis

So, if you did it at the cad, why not do it directly with inventor... .

exactly as you say... but I have verified that the thickness remained constant by trying in half... you see that I made a mistake!? ! ?

Unfortunately I don't know how to use the inventor but I wonder ... can I proceed with the same logic?
do the two floors and then with the inventor loft join them?

Thank you.

No, I didn't say that the thickness isn't constant, it's the profile that's not constant, and then it creates a thickness other than that designed, but above all elliptical rays, which are probably the cause of non-explication.
use the same logic with inventor?
no.with the same procedure would give you the same mistake.
You can do something like that though:
in inventor, in the sheet form:
1)Made the sheet thickness,
2) you need to draw only profiles (internal or external), without drawing neither thickness nor rays, always on two different planes as you did in autocad.
3)convert in modeling and make a loft of surfaces.
you should have at this point a figure made of surfaces of your bent.
4) Now it is mandatory to collect the edges where you create the folds, using radius=thickness if you have the profile inside; radius = thickness*2 if you have it outward.
5) Once this is done, use the thickening command, choose in this "superset" command and thicken the thickness in the appropriate direction.
6) sheet metal reconverts and at this point should explain the development.
What I wrote, maybe it's not the fastest way to do your piece, but it's the one that has the most logical way you did before with autocad.
I still use this system.
And then you let me know... .
