Hi Danny,

Actually, you don't have to do that, this kind of projection is also already built directly into Trim.

It will if the result of the projection is just one curve, like if you use Mode: Closest pt for the projection. But this will be pretty awkward, you will have to keep both the old curve and the new curve around.

History needs to be tuned up some more for that to work very smoothly.
