Digital Three-Dimensional Labeling System of Product Design Information Based on MBD

摘要

MBD (Model Based Definition) technology is the development trend of digital design and manufacture. Design information includes geometric elements, annotations and process attributes. In the paper, the focus is concentrated on digital three-dimensional (3D) labeling of annotations. The 3D labeling system of product design information is seamlessly integrated with NX platform to define digital information of a 3D product model. The Key technologies of the 3D labeling system realization on NX platform mainly includes transformation of space coordinates, reference plane construction based on solid modeling and 3D dimensioning. NX internal program mode is adopted where the developed program is compiled and linked to generate the dll file whose codes are small and whose connection speed is fast. Integrated digital definition of a 3D model shortens product development cycle and improves product design and manufacturing efficiency.
