Looking for a way to achieve this functionality in Houdini:

Link to 3dsmax docs for illustration... [help.autodesk.com]

Very useful in a lot of situations. Can't find nodes that offer this, but my experience is very limited.

This is nice, but the biggest problem it has it works only on quads. That thing in 3ds max can be used on CAD geometry.
I'll try to see if I can post some screenshots of what I used it for.

Ah, I see. That's nice. Yes, Max has some nice things I would like to have in Houdini. Like the conform Modifier.

I don't believe so. I am working with cad models, so I don't see how it would help.

Have you tried labs uv-transfer?
Input:
1.any spline like object
2.corresponding spline

create a clean sweep from the spline with uvs and use uv-transfer.

This is quite handy. Thanks!

Sure

It can be done in VEX aswell (without uv-transfer) using an orientated spline. The uv-coordinates can be extracted from the (xyzdist) captured values.
