CAD环境下实现零件图尺寸的自动标注

Size Automatic Dimensioning of Parts Drawing in the CAD Environment

介绍了机械零件图尺寸自动标注系统的整体设计思路,阐述了该思路实现过程中的各个关键技术,包括:如何自动使标注的尺寸按方向进行分组、如何在每个尺寸组中自动完成尺寸优先级设定、在CAD环境下如何实现尺寸标注在零件图上的优化布置等内容,并给出了相应的程序流程图。

The overall design concept of machine parts map marking system automatically size was introduced. And the various key technologies in the process of achieving, including how to make the automatic marking devise by the direction, how to achieve the automatically priority in the CAD environment dimension, how to map parts of the optimal layout, and other content were discussed, and last the corresponding process flow chart was given.
