Creating multiple folds on 1 face

[Anonymous]

I am trying to make a sheet metal part that has flanges folded down on one side and then folds running orthogonal to those flanges to make a somewhat curved have tunnel if you will. See model. Inventor 2018 won't let me make the folds on the face I previously folded the flanges from. What should I do?

Are you checking the dimensions as you go?

Also, where are you getting the information for Thickness and Bend Radius?

Thanks again for your sensed and constructive answer,

i understand my fault about the dimensions

i had not checked the dimensions after made the flange cause i thought them come up right,
now i'm  understanding also  the tickness has to be considered carefully,
i would like to know how you choose the thikness of 5 mm and radius ?
because i don't really know where i can get it or how i can understand this 2  parameters

indeed to me it seems like a math issiue also missing knowledge

I dimensioned the sketch of your original file.

It is common to use a Bend Radius equal to Thickness.

Thanks for your reply JDMather

after a few improvement i got this, quotes are not all perfect but i'm at the last step, "see attach"
im trying to use the mirror but i cant move the pats close to my primary component and thats weird, i changed  many workplane but those still to far
