Hi Chris,

 

you don't actually need the If() statement, it already evaluates to a boolean.

 

x < 1e-12

 

does exactly the same thing.

Hi mxmln,

 

you use the [Pull Point] component to measure the distance from each point to the nearest curve. If this distance is very small, the point can be considered to be on the curve. Don't compare the distance to zero as you'll likely have to deal with some faint noise in the number accuracy:
