Design for Virtual Laboratory of Mechanical Drawing on Web

This paper discusses the design for virtual laboratory of mechanical drawing, and analyzes the characteristic of mechanical drawing virtual laboratory and the requirements for virtual laboratory, select design platform for virtual laboratory. The method of solid design is discussed in detail. The data structure and the algorithm of modifying data with real-time deformation is designed. And the operating interface with strong interactivity is designed. And at last, a virtual laboratory of mechanical drawing base on Internet is designed.
