Hey guys,
thank you so much for these fast answers!

Michael, I´m sorry for my bad english, but you got it, that´s what I tried to say... I understand the problem- and your solution!

Phiro, thank you as well! I will try it like that, it looks really realistic!

I love this forum, thank you so much and have a nice day!

Hi Phiro,

Can you elaborate the flow process here a little more?

Marek

Hi Marek,

I used Koi's file to have the profile he has made.
I made a boolean union to have a single profile.
I rebuild the curve to avoid the problems I could have with small edges next.
Now this is a seamless curve.
I extrude it to have a first solid. This solid is flat.

Next, I made the two red curves to do the flow by curves process.
for the non linear red curve, I made it with three lines joined.
I filleted the result and moved the points to have non symetrical fillet. This looks more realistic bending of metal.
With the first solid I flow it using the two red curves.
It gave me the second solid.

I use the same process to do a third solid using the second solid and the pink curves (curves made with the same method on the other axis)

I have redone it and I post the file here.

Something like this ;) (sorry crossing posts)

Thanks Phiro and Pilou,

Only now I noticed why I didn't see the Flow command work.
The new objects matched in those already made.
After I hid the 2nd and third solid I saw Flow command perfectly bending the source object.

Thanks again!
