Dear Matt - tpsDig does that, you can draw a curve and then right-click to re-sample by length so you could always select 10 points, and that would give you points at the intervals 10%, 20% etc. R.

The data would be in paired xy coordinates. For example, if I have a curve made up of (x,y) points that is 10 cm in length, I would like to determine the coordinates of positions on that line at 10%, 20%, 30% etc. (i.e., every cm) of the total distance by interpolating between the coordinate pairs I already have.
