基于AutoCAD VBA二次开发智能标注形位公差

Smart Dimension of Geometric Tolerance Based on AutoCAD VBA Secondary Development

针对AutoCAD软件原有形位公差标注模块存在的不足,利用软件自带VBA开发工具,对形位公差标注模块进行二次开发,在标注合理性和规范性方面对模块进行改进和完善;使用ADO数据库连接技术将形位公差数据表嵌入模块,实现智能查询标注,扩展了形位公差标注模块功能;通过CAD菜单定制,实现形位公差标注模块与CAD无缝集成。

Aiming at existing deficiencies of original geometric tolerance marked modules of AutoCAD software, using VBA development tools, the paper was made secondary development to smart dimension of geometric tolerance; improvement and perfection the module in terms of annotation rationality and normative; using ADO database connection technology will shape tolerance tables embedded module, intelligent query annotation, expanded the form tolerance tagging module function; through the CAD menu customization, the paper was realized the form tolerance tagging module and CAD seamless integration.
