这一变化源于微软对VBA技术的逐步弱化，以及Autodesk向更现代、更高效的开发平台（如.NET）的战略性转型。然而，对于大量历史遗留的VBA代码和依赖这些脚本的工程流程来说，64位环境下的VBA支持仍然至关重要。
Locate AutoCAD 2013 and look under the section.
When using Windows API calls via the Declare statement, 64-bit VBA (VBA 7.1) requires the explicit declaration of the PtrSafe attribute. This informs the compiler that the statement is safe to run in a 64-bit process.
Manually mounts an external .dvb macro project into your current session.
：强烈建议将VBA项目逐步迁移到.NET平台，以获得原生64位支持、更好的性能和更现代化的开发体验。这不仅是对当前功能的优化，更是为未来AutoCAD版本的持续兼容所做的战略投资。
The integration of the Microsoft Visual Basic for Applications (VBA) Module AutoCAD 2013
Because Microsoft does not provide 64-bit equivalents for many of these older controls, forms containing them will fail to load in AutoCAD 2013 64-bit. To fix this:
Navigating to the "Updates & Add-ons" section associated with legacy product entitlements.
Choose the installer file (typically named AutoCAD_2013_VBA_Enu_Win_64bit.exe or similar, depending on the language pack). 2. Installation Process Close all running instances of AutoCAD 2013.
This code creates lines radiating from the origin. In 32-bit environments, execution is noticeably faster than in 64-bit environments due to the inter-process communication overhead.
The specific file required for this architecture is typically named AutoCAD_2013_VBA_Enabler_English_Win_64bit.exe (or the equivalent language string for your localized version). Step 3: Execution and Setup Close all running instances of AutoCAD 2013.
