Abstract

It has become a tendency to utilize the advantages of multi-platform to corporately solve the design problems of complex products. To handle the issue of the assembly models that losing the assembly constraints and modelling logs after exported in neutral format from CAD/CAM platform, and to enhance the editability of the neutral-format models loaded in alternative system, according to the standard No. ISO 10303-109 that describes the kinematics and geometrical constraints of assembly model, this paper presents a method that marks the geometrical constraints by the PMI modules, and records the assembly models and constraints through STEP+XML files, which guarantees the integrity of the assembly information while the models are reconstructed or exported. To verify the feasibility of this method, an executable module based on the NX is developed, and the data structure of the XML files, used to read or write the assembly constraints, is designed and actualized. Finally, in accordance with the test results of the four kinds of cases, this method can effectively help designers to solve the problems of constraint information loss for the assembly models under the cross-platform cooperation.
