I am wondering if there is a way to figure out what side of a curve a point is on? I hate to be the guy saying “In Grasshopper, blah blah blah”, but In Grasshopper, there is a component called “Curve Side” which tells you exactly this. I have been doing this for the time being:
But this really only works if the points are clearly above or below the curve. In the case of more spliney curves, this doesn’t always work, because even if a point is technically above the curve, it’s closest point may be below it. Thanks!
