AutoCAD VBA projects can be loaded using AutoCAD interface menus or commands (VBALOAD), or loaded by programmatic control. A more general way is to create a boot menu file, use the menu controls to load various VBA applications, and execute macros in VBA projects. Create and edit drop-down menu groups. You can usually edit the original AutoCAD file with Auto LISP language, or you can use VBA to develop a new menu group file, and automatically run the macros in VBA project when AutoCAD starts.
4 Conclusion
AutoCAD VBA, as a secondary development tool for AutoCAD, can run in the same process as AutoCAD graphics. With ActiveXAutomation, you can manipulate almost all AutoCAD objects. At the same time, it has most of the VB language functions, can manipulate various database software, and perform database programming operations, so that it can operate the database across the application in the AutoCAD system and exchange data with the database. At the same time, the combination of VBA and Auto LISP programming language makes it easier to develop AutoCAD and PDM integration interfaces. This integrated development method of AutoCAD and PDM is an effective mode for realizing the integration of enterprise information system technology, which is very suitable for the development and implementation of information system for small and medium-sized machinery manufacturing enterprises.
