sheet metal

[maria777]

Hello, everyone. I am new on this forum ... a greeting to all

I have a problem with the development of the plates... for example, when I have some pieghie succesive the development for the first 3 folds comes out right and for the other not correct.
someone of you can tell me if by accident to set the bending parameters and for this reason the development is not right.
like immpostazioni use factore k-0.3, but I would like to know when using allowance and blindfold deduction, and here what is wrong?? ? ?
thanks to all

Hi.

this is my development I think sheet thickness is 1.5 mm

the odds with rectangle (75 and 72) are from outside to fold center (where the knife falls for us).

greetings
