Intersect/Shape/Region Union

Region Union allows you to combine multiple overlapping curves onto one complex shape.

In my example, I randomly distribute a curve on a surface, and then using Region Union create a complex curve from their intersections. First, GH generates a number of points randomly on a surface (set the surface in the upper right, change the number of points with the labeled slider). Next, input your curve of choice into to the curve node; GH extracts the center point of the curve and places one at each of the points that was randomly generated in the first step. Finally, bake the “Region Union” button to create a curve of the initial curves’ overlap. Group them when you bake to keep all the small center pieces in place.
