I need to bend a part so that it follows the contour of a surface of another part. Is this possible? I need it for the general case. I can write an add-in to help with the process if needed but I'd like to find the easiest way.

Example:

Suppose one has a curved surface S of a solid body with a groove/slot in it. Another part, say a "T beam", is to be mated with the solid body at the groove. The T beam should be stretched to fit in the grove(for example, mating both ends should "stretch" it) and the T beam should be "warped" to the surface.

Any ideas?

Thanks
