Cylinder with Grapher

Hi! I am working on a cylinder, made by a rail revolution, based on two circular rails and a line with a map graph. The idea is that both ends of the line are always on their rails and the rest on the curve can change by the grapher. I know it is a simple figure, but for some reason it worked, than it stopped working and shows me an error. Does anyone know what may be happening or is there an other way of making it?

Thanks Kim!

When you use the Cull Index component, is it for selecting the points that dont move with the graph? Considering a future design that has more geometry limitation.

That’s what you wanted to do… isn’t it?
