Design and Realization for Intelligent Software System of Engineering Drawing Exercise Collection

This paper discusses the design for Intelligent software system of engineering drawing exercise collection in detail and analyzes the requirements for graphic support platform. for engineering drawing exercise. An open graphic library included exercise library, answer library and solid model library is presented. An intelligent processing strategy for automatic check exercise based on graphic feature structure and shape matching methods is discussed. An intelligent processing strategy for automatic check exercise is discussed, which includes analysis of requirements for automatic check exercise, automatic check processing strategy and an shape matching method based on graphic feature structure. At last, an intelligent shape matching algorithm based on forward reasoning is presented.
