Curve/Utility/Project (P3 Elias Lewis 03)

The project tool is used to place curves on a polysurface. This is helpful to place a curve on a rounded surface. The three necessary inputs are the curve itself, the polysurface the curve will project onto, and a directional vector to orient the curve towards the object. The vector can be taken from a curve or the vector function in Grasshopper. By default, the curve will also appear on the back of the object. If the curve goes off the edge of the surface, the curve will mirror itself and close to make one curve. One function that can be used following the project tool is the extrude tool to make a surface protrude from the surface.
