how can it be that by creating the model in the sheet metal module folds the accounts back with the 2d model of departure, and at the time when I apply the development in plan the total share disconnected of about ten millimeters from the drawing taken into consideration? Will the 2d model be wrong?

I have rechecked the first 3d model you post and there are differences with the 2d :how can it be that by creating the model in the sheet metal module folds the accounts back with the 2d model of departure, and at the time when I apply the development in plan the total share disconnected of about ten millimeters from the drawing taken into consideration? Will the 2d model be wrong?
the extreme sides are 43 mm instead of 39 and the other 2 are 44 mm instead of 40 now with an internal radius of 4 mm the development is 257.3 mm

ciao dandao thank you for the clarifications, but I'm not able to understand why when I click on the command you recognize, it gives me the message that you can see in the pdf I'm posting, preventing the successive steeps!User1

But can someone help me figure out where I'm wrong? I posted pdfs explaining my calculations that do not go back with model 2d! I ask for help to all of you!

it gives you that error because my procedure is valid x a detail like that posted by you at the beginning created with part desig and not one already created in sheet metal

Thank you, dandao! I couldn't see all the pages, from the third on, you can't see anything! How about those calculations I did? I'm out of 0.5324mm, what could I have done wrong?

I think I found the solution to the problem! However, if there's someone who's experienced in the folds, I'd be very happy to exchange some opinions! I attach files with formulas and caclols!
