使用AutoCAD命令只能标注或修改一般外观形式和文本内容的尺寸,而对于工程图样中具有特殊外观风格和特殊文本内容的尺寸却难以标注或修改.针对这一问题,使用VB编程工具设计了一个用于修改各类尺寸外观属性和文本内容的多功能尺寸编辑器.所修改的尺寸文本采用了格式控制字符和尺寸属性值及变量组合而成的形式.多功能尺寸编辑器具有界面直观、操作简单、修改效率较高的特点,其不仅具有修改尺寸外观一般属性的功能,还具有增加前缀、后缀、尺寸公差、公差带符号、配合代号、机械专用符号和自动检索极限偏差等属性功能,完全实现工程图样中具有特殊风格和要求的尺寸的快速修改.%Dimensions with ordinary appearances and texts can only be dimensioned or modified by using AutoCAD commands, while it's quite difficult to dimension or modify dimensions with special styles of appearances and special texts in engineering drawings. To solve this problem, a multi-functional dimension editor is designed, using VB programming tool, to enable changing various dimension appearance properties and texts, in which dimension text to be changed is in the form of a combination of format control characters, dimension property values and variables. The multi-functional dimension editor, with a direct interface, is easy to use and efficient to change dimensions. It not only possesses the function of modifying ordinary dimension appearance properties, but also achieves adding prefix, suffix, dimension tolerance, symbols of tolerance zone, fit symbols and specified symbols for engineering drawings, retrieving limit deviation automatically, etc. .It can completely realize the quick modification of the dimensions with special styles and requirements in engineering drawings.
