It was said that, “by default, a new connection will erase existing connections. Hold the SHIFT button while dragging connection wires to define multiple sources.”
However, even though I was not holding the Shift button, the existing connection still remains the same position. That means I need to manually “Ctrl + Drag” disconnect the previous connection every time, which is troublesome. I am using Rhino 6.5 and Grasshopper. Is there any solution to my situation? Thank you very much.
