基于特征的彩电机壳造型结构设计

The Feature-Based Design of the Shaping Structure of the Color TV Set Case

就如何在彩电机壳造型结构设计中利用特征的概念进行了讨论;根据设计人员的设计思维过程,选择适合彩电机壳造型结构设计的特征;针对特定的CAD环境,描述了造型结构设计中利用特征的诸如特征识别等有关问题.

The design of the shaping structure of the color TV set case is complex and time-consuming. The CAD methodology using the features concept for the design is discussed. A 3-D model consistent with the mode of thinking of the designer and the design features is developed. Using this model, the designer will be released from routine operations and enabled to devote his talent completely to the creation of new patterns. The generating process of a 2-D view typically involved in a 3-D pattern matching between feature definitions and a B_Rep solid model is also discussed. Feature recognition is described for a specific CAD environment.
