I try to wrap a sketch on a surface. I tried it with 'project to surface', but is not really wrapping, like when you cut something out from paper on put it on the surface. Some dimension are changed. For me it is really important that the dimension are NOT changed, because I make a so called tongue drum from a gas bottle and the length is important for the frequency. Here is an image:
Also tried with embossing, but it does not accept the surface as input.
Anybody knows a solution for this ?
there is no way, today (at least that I know of) to do this. We are working on enhancements to Emboss to support surfaces like this, but that project is still under way.
Every "wrap" or in more technical terms UV mapping onto a non-developable surface (compound curved surface) will cause UV stretching. That is a mathematical necessity.
If you map the rectangle in your screenshot onto the surface below, the sides will curve. You might be able to keep the length of these curved sides the same, but the surface area will change as is now isn't flat anymore but curves through space.
Or you might want to keep the surface area constant, but then one, or both side will have to change in length.
You may want to provide a bit more detail on what you are trying to achieve.

The double bend sheet metal technique can do that. Starts about 20 minutes into this tutorial.
I'm busy to make something like this:
The most important distance is where I put a red line (determine's the frequency if you hit it), that's why it is important that it is a real 'wrap' from a plane sketch. The width of the cutouts or less important but as width as possible.
You did not supply a model so I made a sample. Take a look at the video and see if the process will work for you. Model is attached.
