Abstract: This paper introduces the Charles Loop’s scheme into the synthesis of product design，and proposes a PD-LS algorithm for constructing product prototype based on location subdivision module.This algorithm does iterative interpolating ghost points on location using location subdivision principle，in order to hold different density on different region，which can prevent distortions and decrease the density of the whole mesh.

Key words: product design, product prototype, location subdivision
