ah yes...some context would help, sorry.
What I need is to do is apply the workflow solution you shared using the cloner and plain effector, to all of these shapes. I can get the length of the curved spline by hitting Mode < Project Info, then I can create a spline of equal length that's flat that represents the second flat state. so all I need is a way to apply ur workflow to all my shapes so I can make them flat. I can see that u used custom color fields in your example but I'm not sure how to apply your solution to all my splines. sorry if that doesn't make sense...my wife tells me that I'm a bad communicator...hahaha
