Hi Rudl,
Welcome to the forum Smile
To make the snail, you should go to the "Parametric" section of K3DSurf and enter the following formulas in the corresponding area:
Quote:
X():u *cos(v)* sin(u)
Y():u *cos(u) *cos(v)
Z():-u *sin(v)
[u]:0, 2*pi
[v]:-pi, pi

See the screen-shot for more information.
