Abstract: Persistent naming of topological entities is one of the key technologies for developing independently-copyrighted parametric feature modeling systems. A method and the relative mechanism of the complete hierarchical naming has been proposed progressively from original names to reference names. In the first step, the general mechanism of original name design and naming propagation was analyzed. Then, reference name with hierarchical structure are constructed by comprehensively leveraging the effective information from the design process such as feature direction, local topology and so on, and the identification results are obtained by parsing the reference name based on the proposed principles of activation feature, symmetric activation feature and subset relationship. Finally, an OpenCasCad-based prototype system was developed in order to verify our method. Experiments demonstrate that our method can effectively address the ambiguity problem of referencing topological elements. In addition, our hierarchical dynamic mechanism has the quality of superior scalability.
