The Polyarc tool in Grasshopper can be used to connect a number of points together with arcs. The points can be made in Rhino and then selected in Grasshopper or they can be made from the point command in Grasshopper. After the points are picked, the line to the V plug can be attached and the poly arc will be drawn. Next, a tangent vector can be drawn with line and inserted into the T input. Finally, a line to close the polyarc curve can be created and plugged into the C spot.
