This is an intermediate grasshopper3d video tutorial, on how to animate a set of curves, by having them be gradually drawn out. The concepts presented here can be extended on many other cases of Grasshopper animation.

The methodology is being presented in Rhino 6 & Grasshopper 3d 1.0.004, but works similarly for Rhino 5 & Grasshopper 0.9.xx.

This definition was written in GH v 1.0.0004. Please use it “as is”, it does not come with warranties.
