摘要
本文介绍了采用辅助投射法和亲似对应法求相交的原理和方法,并与辅助面法进行比较,指出其应用范围:同时又借鉴了求曲面立体相贯线时辅助面的选用问题,以便在实际应用中选择最合理的方法,达到简便准确作图的目的。
Principles and methods of finding intersections of geometric elements such as auxiliary projection, and affine correspondence are reviewed and compared with the auxiliary plane approach whose scope of application is pointed out herein, problems on the selection of auxiliary plane for the construction of intersecting curve resulted from curved surfaces were taken as reference to select the most justifiable method for convenient and accurate construction.
