As mentioned in the rhino file I want to bend my object along that white curve line for that I have mentioned the arrow as well for better under standing so I tried bend command but that is strachin the object so anyone can help me with that.
I am sharing the rhino file here

You can achieve it with FlowAlongSrf, and FYI.
hello @jessesn
I tried that this works fine but for some of my other shapes the shapes are getting stratched in the command after complete so can you check that I am sharing my rhino file here also so you can have better idea about that also and let me know if there is any possible solution for this.
Or anyone has solution related to this please let me know I tried preserve structure and all but not working proper.

Post a file which includes the unsatisfactory results as well as the input objects.
Just do flow along surface with the STL group and base and target curve you get the idea as placing all limits the file size so that why I have not put that
It works fine on my side, and for your reference.
It works - but with a large amount of distortion.
Objects to be flowed.
Flowed on original ring.
I used RebuildUV to rebuild the ring in the V direction with 30 points. Maximum deviation from the original ring is less than 0.002.
Flowed on rebuilt ring. There is much less distortion.
There is much less distortion when flowed on the rebuilt ring.
The cause of the difference (my interpretation):
The original ring is degree 3 in the V direction with a fully multiple multiknot. Above the multiknot the cross-section of the surface is an arc. Below the multiknot the cross-section is a straight line.
FlowAlongSrf uses mapping in the UV parameter space, not the “physical” space.
The ratio of the arc length to the straight line length in “physical” space is 7.50.
The ratio of the arc length to the straight line length in “physical” space is 4.85.
That difference results in the distortion.
When the surface is rebuilt in the V direction the multiknot is eliminated, and the V parameter tracks with the physical distance. That reduces/eliminates the distortion.
