工程图学CAI课件的研制与实践

Research and Practice of CAI Software in Engineering Graphics

本文根据工程图学的发展和教学实践要求，为了提高教学质量，对“相贯线和组合作”CAI课件的系统设计和程序设计，以及二维和三维图形间的内在规律进行了探索，并给出了一种CAI课件的结构模式，它操作方便，形象生动而直观．

According to the development of Engineering Graphics and the demand ofteaching practice,this paper explores the system and program design of 'In-tersections of solids and combination solids'CAI (Computer-Aided Instruc-tion)software,and the internal rules of two dimensional and three dimension-al drafting. It also offers a structure mode of a certain CAI software,whoseform is vivid and visual and operated simply.
