After Twist, that was Jerk, no? It's Rock'n Roll!

Step by step, I find again the functions that I liked in Amapi 3D.

It goes to miss some functions to create skins with a lot of irregularities; and why not, commands of erosion & corrosion (I don't know if it's possible with NURBS).

I would like always, a nice choice of bevels on letters (LOL!).
Have a good day.
