I’ve found a strange little bug in Grasshopper. I cannot reliably set (capture) lines from Rhino to Grasshopper–especially in the Z’ed axis. I can set (capture) a point, but when I want to read a line, it always asks me to instead draw one. I’ve seen bad parameter behavior before, but it just won’t let me capture a line at all. It will allow me to capture it as a curve, but not a line.
Right after this screenshot, it will ask me to just draw a line.
