It's a bit hard to tell, but I'd say it looks like two simple sketches projected together. Perhaps a circle on top and a shallow arc on the side.

can you make a tutorial?

Swamped right now, but it's fairly simple. Sketch 3/4 of a circle on the top plane, sketch a shallow arc on the right plane (same length front to back) and then use the intersect tool to intersect the two.

shallow arc?

Large radius, fairly flat.

Sir,

very nice can I get the video?

Please try this with the information posted. Maybe you can post the video once you understand how this works?

Funny, I came in this morning with this on my mind and decided to make a quick model. Then I find that you've already got your solution.

Oh well, I made the model so I decided to post it anyway. It's in WF4 so pretty much anyone can open it.

The challenge has changed slightly as the 2 free ends are now straight.

This time I used a wrap feature to better preserve the radius.

Creo 2.0 model attached.

very nice work is that possible make video?

kind regards,

The wrap feature is discussed in this video:

Closed and Ground Spring - Alternative to Helical Sweep

You have to be careful about running the ends beyond the surface. If you check both options in the wrap feature, it may ignore it. However, I have also had it fail. I measured the length of the surface to use in the "U" shaped sketch in the included example.

One thing, depending on the desired result, you either want a wrapped curve, or a projected curve. Wrap does exactly that, preserving the overall length of the curve. Project does what Antonius did first with the intersection of two curves, which will stretch/distort the overall length.
