Propagation of design change between different CAD by using duplicate design procedures

摘要

Design change can become difficult to propagate when the CAD software used in industrial design and mechanical design is incompatible. Different CAD systems typically adopt neutral formats as the standard form to conduct exchanges between files. Because these neutral formats cannot keep the details of the design features, this work presents a novel approach to achieve design change propagation. First, the macro type passing data (MTPD) is employed to record design procedures, and the similarity comparison is adopted to identify the differences between two input models for the mechanical design. By noting the differences in corresponding elements in both models, designers can adjust the MTPD from the old mechanical design, which was added on the first input model and applied onto the following input model. The design change propagation between industrial design and mechanical design is then concluded. This modified MTPD can duplicate design procedures in both standalone and server–client edition in our research. Users who only use a web-page viewer can now also view the propagation collaboratively.
