great stuff that you are sharing here. Big thanx for that. I don´t understand where´s the difference between the 2 splines ["path"+"spline"] in both examples. I tried to delete one of them and i see the effect, but when i try to rebuild something like this for myself, i don´t know how to start. Did u draw both of them and put them in the sweep nurb or what ??? Maybe u write a little litte little tutorial how to rebuild that ? Or if anyone other who knows would do that... that would be great.
