Didn't you pointed out that using path "arithmetics" would be a perfect solution to the problem. Well, here too! Just use a grid path from the axis: l = f.path.intersect(g.xgridpath(0.2))[0][0] Note that l will be a normpathparam instead of a simple length, but this is a feature ... and you can do funny things with those parameters (like adding an arc length to such a parameter).
