Take a look at the attached file. Just edit the user parameters and the CoilForm sketch to your specs.

My need is to create a coil with a circular-section wire.
But the section of the coil itself should be elliptical.
how can I do it please?
Bit confused by this. I think you want an elliptical coil, I'm unsure about the bit about section.
Try the attached. I don't really like it but using path with guide rail doesn't keep the round section.
This is with a guide surface.
And this with a guide rail. Creates a single surface but very distorted. You might get better results is the ellipse is more circular.

Just for reference this is what I get with a more circular ellipse (45x50) and just using a guide rail. File's attached.

Here's the file I posted to your other post. Note, you could save this as a part then insert into other designs to reuse so you don't need to recreate each time.

I've found a bit of a problem. This method using a Sweep to create a path tends to fail if you don't use full turns. The use of pipe rather than a sweep for the wire is good but doesn't seem to work well with partial turns.
With 30 turns I get a good coil.
But with 29.985 like your sample design i get this. Probably only a display problem but using detail controls and setting the mesh to high doesn't help.

@TheCADWhisperer Don't know if you did this for a reason but having the sweep the same diameter as the longest side of the ellipse means you get a broken path and a segmented pipe.
If you make the sweep a bit bigger you get a single path.
and no segmentation.

Thanks to you guys really by heart. I was able to make it. Without your hint, it was for me impossible
