I found half a dozen offset 3D curve threads but the solutions didn’t quite fit, I’m somewhat trapped in using the Offset Polyline component and it’s acting like a 2D projection. [image] [image] [image] I was expecting (hoping?) it would look the same from above, but follow the peaks and valley…

Use points to make a mesh, turn that into a brep and project the offset curves to it? (SLOW) [3d offset_2021Jan23a] 3d offset_2021Jan23a.gh (77.2 KB)

Offset 3D curves in the XY direction, following Z height?

That’s great Joseph! I need to smooth out those verticals to make it more organic and less faceted but that’s great.
