This ought to be really simple but apparently im just dumb…
I have a bunch of curves that make up city streets. A separate list shows all the points where there are businesses. I need to find a point on a street curve that is closest to each “business” point and connect it with a path. In other words, each business needs a little pathway line that connects it a section of road closest to it.
For some reason the component is just giving me the intersection points of each street curve and then connecting that to the points.
A curve in Rhino is topologically always a line segment. It may be bend or kinked, and the end-points may touch, but there’s never any gaps in the curve and never any branching points. During a join operation the curves are joined together into larger curves one-at-a-time. As soon as some curves form a closed loop (i.e. when the start and end-point are coincident) that whole loop is removed from the set of joinable curves.
It is exceedingly unlikely that a network like this can be turned into a single curve, and even in those rare cases where a solution is possible, it is unlikely that Rhino will come up with it.
