So I have been messing around with the record history button today. Just wondering if anyone else has used it yet. It seems like a great little tool to bring parametric modeling into Rhino.
Anyway here are some of my results from this quick play.



Results of adjusting the original curve 1: Vertical move 2: move control points 3: Move curve along XY axis.



Scaling the center curve to twice original value and then in 2nd image moving curve.


This was merely a simply test to show a new command. What I’m interested in is the application it has to others and their experiments. Has anyone used it yet?
