基于知识的平面组合体CAI二求三系统研究与开发

Computer-Assisted Instruction about Forming the Third Drawing of Plane Group Object Based on Knowledge Developing Intelligent System

对于工程制图CAI课件中二求三问题,以往的课件都是针对题库中的题目进行的,对于任意输入的题目,就无能为力了。基于面域基的概念,研究与开发了平面组合体CAI课件由两视图自动生成第三视图的方法。并在程序上得以实现。

Forming the third picture based on other two drawings in the past courseware depends on the problems that are stored in picturebase.It's difficult to do with the arbitrary problems.Based on the conception of basic surfacearea,the method on Forming the third drawing based upon the other two drawings was presented in intelligent detecting system of computeraided instruction about engineering dawing.It has been realized by programming. 
