Abstract: The paper establishes a computer algorithm for solid modeling of 3D helical-body based on the analysis of form mechanism, mathematics model of helical curve, and based on solid modeling methods & shape of 3D helical-body. The algorithm theoretic foundation is sweep representation thought in solid modeling and limit thought in mathematics. Its application practice shows that algorithm has strong application value and nice foreground.
