摘要
三维模型工程化是将实体模型的结构及位置在空间坐标系的3个平面上建立二维映射关系,得到工程图模型,再辅助以其他工程图要素如图框、标题栏、技术要求等。从建立货架类产品层次化结构出发,研究如何按层次化结构建立三维实体模型在平面上的二维映射关系及相应的映射算法。
3D model engineering means that 2D drawings can be got by means of projecting the structure of 3D solid model on 2D plane, and the other engineering drawing elements such as drawing frame, caption frame, technical requirements can be put on 2D drawing. This study explores how to set up 2D projecting relationship of 3D solid model within 2D plane, based on layering structure, and how to project in the process.
