Hello!

I am a self taught Rhino user, so usually resolve problems as they come up with the many tutorials and threads there are available…But i have come up against a brick wall of my ability. I suspect that there is an easy way to find out and that i am just looking and thinking in the wrong direction.

I am trying to model this surface (see 1st two pics)

I have created linework of the high and low points of this surface in the hope of being able to either patch through the adjusted curves, or move the points of a surface along the linework. The latter seems the simplest and most logical solution but i am just stuck.

Here are some screen shots of the linework i have and the initial adjusted peaks. Patching through this seems to have a strange amount of noise/ inconsistencies rather than smooth curves, so maybe isn’t the solution.

I suppose the main question i have is whether it is possible to edit the points of a surface along a drawn curve? ie select a surface along the ‘peak’ lines and move up the required distance.

I would really appreciate any help anyone can give me, i understand i might be barking up the wrong tree so feel free to say so.

Thanks.
