Hi there I was wondering if anyone has had any success in extracting sets of U or V lines from a mesh?
it’s relatively straightforward doing it for a nurbs surface but i’m looking to do it to meshes because sometimes I am not able to get clean nurbs surface conversions from other software.
any help would be greatly appreciated, thank you

You can use the WarpWeft component (under Kangaroo2>Mesh) to separate mesh edges into 2 sets for the different directions
Great thanks for that @DanielPiker
Funnily enough i’m actually doing this for the reason of trying to emulate this you created!
Did you use a similar process to get the UV lines on this one and how did you control the spacing of the lines/contours? …or did you use some other magic haha
here’s what i’m working on it’s a hand draped from blender
For something like draped fabric I think using the warp/weft directions of the quad mesh is a good way to show the shape of the surface in an etching style.
For that hand image I only had a triangulated mesh, and got the curves by taking intersections with a set of stacked curved surfaces roughly perpendicular to the directions of the fingers.
Building these surfaces was rather manual though, and since then I’ve done this work, which can be a way of getting these sorts of curves in a more automated way:
