Hi,

how to make all points divided within a curve to start from the same point regardless the curve cut.

You can make one long “template” curve (covering all the other curves) and divide that curve with perpendicular frames.

Then all the other curves can “intersect” with these (infinite) frames/planes and so you end up with points on each curve being spaced exactly as the “template” curve.

thanks RIL,

this works on a straight surface while the surface I am having is double curved. you can see the 3D model here.model.3dm (76.3 KB)
