Abstract: To solve the problem of curving eyeglasses’ temple automatically, this article analyses the basic structure and feature of eyeglasses’ temple according to the theory of features modeling, and defines the data structure by CSG. Lastly the parametric modeling and curving algorithm of eyeglasses’ temple are set up, which provides a method of theory and technology for eyeglasses’ CAD.

Key words: eyeglasses’ temple, parametric modeling, curving algorithm, feature modeling
