Ciaran, I'm attempting a similar approach now. I think it will be the most efficient way actually. I'm working on something now which generates an array with a dense set of step positions of the curve and a conversion of 0-1 to equal a relative index on the array. I've tried using Get Geometry Sample and Generate Sample Set but have been unable to get either to work with the density I'm looking for. I'm curious though, is it possible to convert curves to linear curves within ICE?

UV to location on the linear curve should give you a pretty even point distribution... Ciaran On Thu, Aug 1, 2013 at 1:25 AM, Ponthieux, Joseph G.
