TABSf N { C | S } { X | Y | Z } VX VY VZ ZP1 RP1 ZP2 RP2 ... ZPN RPN END

S or C indicates whether the tabulated surface more closely resembles a sphere or cylinder (this information is utilized to speed up the drawing of the surface).

The axis of symmetry must be parallel to the X, Y, or Z axis; which is specified by argument 4.

(VX, VY, VZ ) is a translation vector. The tabulated axial ZPi and radial RPi values are relative to this vector. ZPi is the distance of point i along the symmetry axis, and RPi is the distance normal to the axis.

END terminates the description. The description may be entered on multiple lines as long as a break does not occur between ZPi and RPi for the same i .
