How to wrap a pattern on to a sandune shape


I have drawn a pattern with pl line on rhino and I want to replace the surface of my sanddune with this pattern i.e the pattern becomes the shape of a sanddune. I have got the sanddune surfaces and the pattern, how do I replace it.
Command ‘Project’ does not help, I know there is a UV command but cant remeber the full command name… does anyone know?

Hello - as always, it is impossible to help without a file and some directions of what you want to do, to work with.


I have sent you a link, I did upload it but not sure why it didnt show up.
