Research on information correlativity and inheritance of part drawing and assembly drawing

摘要

The process of product design is the gradual subdivision and iteration of designer's ideas, which assembly design and part design of the product goes alternately. Product information is generated, transmitted and reused in different design phases. Design process of a product goes with flow of design information. In this paper, commencing with research of information share, information correlativity between part drawing and assembly drawing is established, which realizes correlative query of the structural information and the technical information as well as inheritance of technical information between the part drawing and assembly drawing.
