Application of XML on Data Transformation in Product Model

According to the data description function of the XML,a method is put forward by decomposing information to transform the assembly information and geometry topology information contained in the product modeling system into virtual assembly system through data exchange interface.Using XML-based neural file and triangle polygon model file,virtual product model is re-constructed through mapping relations between polygons and geometry elements.The technique mentioned above solves data share problem between CAD and virtual assembly system.A prototype system is developed for verifying the feasibility of the technique.
