Project command not working as expected

Trying to project some roads onto a surface generated as a result of using contour information. But it wont project neatly onto the surface. Any ideas?

Hello - please post a file with the curve and the target object, I’ll take a look.

Hi Chris - this is what I get:

I have not examined the results - can you tell me what to look for that’s unclean?

Some roads seem to be above and then cut under the surface, as opposed to running on top of the surface

Ah, OK - that is because the display mesh on the surface is too coarse - you can tune it up by making that mesh finer:

This has resolved me issue, Thank you for your help!
