change

Good evening to all
I am new on this forum,
I need help
at work a customer sent me the development in dxf of a folded piece and my owner asked me to change the development of the piece in autocad because we don't have its 3d, could someone explain how to change a development without moving the work done on the piece? ?
the piece changing the development and then bending it must match the folded design but I do not know how to change a development in autocad
Please help me are in trouble
rest waiting for your courteous match
Thank you very much

You must:
know how to pick up or stretch the material during bending
made this you have various ways:
you revenues the development in autocad drawing the flat view through projections of the folded piece; Irons, in positive or negative depending on whether withdrawal or extension, geometry making a selection between fold and processing.
models the solid with one of the 3d at your disposal and the more you gain the development by fitting the k.

ask for explanations to the owner or a colleague should not be considered a shame

I was told that on development I have to remove 4mm per fold and there are 5 folds in total
Can you please explain to me how to change the development if I send you an attached png?
my owner does not know how to use autocad and the 3d we do not have it and in technical office I am alone so I was in trouble and for this I ask for help
if you see the png attached the red lines are the fold lines and then on the sheet there are other holes type machining and a rectangular cut
I ask you a favor if you can explain where I have to go to change the development to get the drawing quotas after bending it.
I'm waiting for a friendly match.
Thank you very much
greetings

the holder does not need to know how to use autocad to tell you how to get the development as this is a knowledge of geometric operation and not of cad function; theoretically you could do it also with tecnigraph. . .
However if you have to remove 4 mm per fold means that at each png fold line you have to iron 2mm geometry on one side and 2mm on the other excluding the processing.
then the 40 will become 38, the 50 (90-40) will become 46, and so on
for processing do the tests on the upper holes, these are located in the middle of 50, when you ironed the geometry they will have to stay in half.
