A bottle-neck problem in CAD/CAM on sculptured surface, how to describe its artistic features is presented. It is difficult to describe the geometric information and artistic featuresat the same time with traditional curved surface description methods. A parametrization description for sculptured surface with harmonics analysis method is put forward. The geometric andartistic information can be described through extraction on feature parameters from sculpturedsurface, and how to produce the geometric shape and artistic style with harmonic feature parameters is discussed.
