curves from a divided surface

[Ben]

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.  Is there a way to create individual curves, much
like sections cuts, from the points according to their section plane
instead of one continous curve that intersects all points?
