Feature-based Product Information Processing Technology Research And Application

With powerful geometry modeling, modern commercial CAX software can' t supply engineering application with sufficient non-geometry informationTo get an information model, an approach is to integrate geometry information and non-geometry information into a whole one, on the basis of feature. Master model, which in conceptual field, could be projected to an instance in application field. The instance makes information conversion more convenient. And among CAX systems with different data structure, a neutral media file is used to implement information share.During the development of special fixture computer aided design system, engineering drawing processing module is implemented, which based on the approach of product information processing. The module converts information from 3D to 2D with high efficiency.
