Developed 2D to folded surface 5

[iscariot]

I would need your ideas to achieve to take one sketch from Part Design (made from 2D unfolded view) and fold it on a surface close a to cylinder.
I don't have access to developed toolbar as I don't have the license for it. How can I trick it without this toolbar?
Thank you.

let see if I can explain this one

let say your geometry to fold is simple like a square.

Create a diagonal
Split square, creating 2 curves
Define a law with ref line = diagonal and value = split curve

Create line on curve surface
Create // curve on surface using law

itsmyjob, I don't succed to follow you. I try to achieve something like below.

Would this work with what you have described?

I have the before and after surface and I need to take somehow the geometry from unfolded surface to the folded surface.

I made a rectangle, with the short side PI*10mm. I have a half-cylinder with PI*10 length (radius 1).
I follow Erics suggestion, and on the rectangle I create a random sketch. I then create my diagonal reference on the rectangular surface.
A law is created, with the diagonal line as reference and the sketch as values.
on my cylinder I create a line from one corner to the opposite one, support being the half-cylinder. parallel-line utilizing the very same law...
I attached a warp surface for reference... (the blue one)

regards,
LWolf

I have tried it and works somehow but there are still some issues.
What happens if I make a vertical line? for me it does not work in this case and I have actually a lot of vertical lines.
What happens if diagonal line and sketch don't have same start and end point? for me the result would be completely wrong in this case.
What happens for a bigger circle arc? for me will not work.

By the way, if we would take the lower side of parallelogram and the sketch to make the law, wouldn't I would get more precise output?
To folded sketch has to be made with a parallel of the circle arc in this case.

Thank you very much for the tips, very usefully for me to go in a good direction.

I think that most effective way would be for me to split a complex sketch in individual components and fold each individual curve.
All good for some lines and curves:

I am stuck with curves that cannot be projected as for example one circle:

Any idea how to proceed with curves that would self intersect if I try to project it on a side of my rectangle?

 

[iscariot]

Is it possible to automate the command "Parallel Curve" using a law?
I made some progress but I am stuck:

powercopy?

and for curve that self intersect... cut into smaller one until curves are ok

Thank you very much, I could not have done it without your help.
