ABSTRACT

In the design of existing car body parts, some structures are primarily designed based on mechanical and material properties, resulting in similar but not identical structures. This leads to repetitive design for each project, consuming a lot of time and reducing efficiency. Leveraging the UG11 software platform, combined with NX Open and UFun secondary development technologies, and using Microsoft Visual Studio 2017 and C++ programming language, an automation bridging system for car body target parts and components was developed. The system realizes automatic bridging by selecting auxiliary surface, Angle size of vector ray, relationship between line segment and surface, automatic selection of bridge surface, offset surface, extension and pruning, merging and so on. The system is integrated as a UG plug-in to simplify installation and bring substantial efficiency gains in body part design and modeling.
