Hi Nick, currently there isn't any tool for that, but probably the "rebuild" tool that I would like to add in would be good for that.

It will basically reconstruct a curve by sampling some points along it and then building a new curve that goes through those points.

But it will maybe be a little while before I can get to that one, I don't think I will have a proper place to put it in the UI until after the object properties panel is done.
