When you divide the surface all the points are stored in a single list. The first N points (where N is the number of V-Steps+1) belong to the first curve, the next N points to the second curve and so on and so forth.
If you want to create curves through each sub-set of N points, you'll have to put those N points into a unique data branch (you'll need Grasshopper 0.6 for that, which is currently only available from this forum, the official download site still offers 0.5). You can use the [SubSet] component for this. You'll need to generate a correct amount of SubSet intervals first though, which is the hardest part: http://groups.google.com/group/grasshopper3d/web/IsoCurves_TheHardWay.png -- David Rutten [email protected] Robert McNeel & Associates On Apr 2, 3:31 am, Ben <[email protected]> wrote: > hi all > i'm an arch student with only a few days with grasshopper and have > been blown away with the possibilities that i can imagine but not > realize. > i've taken a "tunnel" like surface and divided it into a large amount > of points with the Divide Surface componet and a couple of sliders for > the U and V inputs.
