The paramplot command takes two arguments, a list of three expressions involving two parameters, and a list of the two parameters.

paramplot returns and draws the parameterized surface; the command paramplot([f(u,v),g(u,v),h(u,v)],[u,v]) will return and draw the surface given by x=f(u,v), y=g(u,v), z=h(u,v).
Input:

paramplot([u*cos(v),u*sin(v),u],[u,v])

Output:
