【Abstract】 Based on the principles of feature modeling,taking the characteristics of shaftlike parts into consideration,feature model of shaft is set up. A feature modeling system is developed. The windows style interface makes the design convenient and efficient. By using AutoLisp language, this system introduces the principle and algorithm of automatic dimensioning about axial dimension. On the base of this system, automatic dimensioning about axial dimension of shaft and parametric modeling are implemented.更多还原
