Hello.
As in the attached photo , I present my problem to you. So I started my piece with the sketch that can be seen in blue to create my sheet metal.
The problem is that when I use the unfolded state function at the bottom of the tree, I don't get the right developed length.
By adding the length of the arch of the arched part and the two 100mm drilled bands, I get, 1365+100+100=1565. and developed me in 1890,....
If you can enlighten me, I thank you.
A priori, like that seen from a distance, I would say that Solidworks adds a loss to the fold that you don't take into account
If you calculate from the outside of your part, do you get a value closer to Solidworks?
Coin 37coin,
My piece is only 3mm thick. So no, it doesn't change much about my length of 1565.
I do think like you. Solidworks must take into account the loss of the curve roundness at the folds that I don't know how to modify. Maybe the process is not the right one? I may have to start from a flat face and insert a fold with a large radius that corresponds to my curve.
I still hope to be able to use the fastest method.
Agree with you@coin37coin
In rolling, it is necessary to work in neutral fibre: the coef K assigned to the radiated fold must be 0.5.
The other plies must have a K coefficient of 0.01 (for the use of inside dimensions).
Thank you everyone
Thank you david be3 with the coef K 0.5 it's already much better.
Drawing 6 thank you for your file, unfortunately I can't open it.
Hello
If it's a curved piece only, the easiest way is to use the bend area instead of the K factor, on the other hand the value of the bend area you have to put your length developed.
Neutral Fiber Radius x ft.
Good luck

Precisely, I am looking for Solidworks to determine my developed length and not the other way around.
Thank you for your indications.
So the best way is that of David be3.
