Abstract :
Feature based design is the main characteristic of current prevailing parametric solid modeling systems. By means of enabling users to build their own feature libraries, user defined features (UDF) provided as an extensional design method can overcome the shortcoming of inconvenience that exists in the traditional feature based modeling system. Traditional UDF representation is implemented either by procedural definition, which represents the features implicitly (J.J. Shah, 1991), or by an explicit representation or enumerative way (M.J. Pratt, 1989; M. Ranta and M. Mantyla, 1993). The paper proposes an innovative approach to the representation of UDFs by extending the common procedural UDFs´ data structure with boundary features. Then a unified feature attachment interface is described. Thus, a unified representation of UDFs is introduced
