The addition in V7 of using curves as a source for comparison points for PointDeviation with the user specifying the number of points per curve is great! An enhancement would be to provide the option for the user to specify the point spacing instead of the number of points as in Divide. I frequently need to check a surface for deviation from a set of curves with the curves having very different lengths. Setting the number of points per curve to provide close enough spacing on the long curves results in excessive number of points on the short curves.
