AutoCAD 2014 was a watershed release. For the first time, AutoCAD 64‑bit began using Microsoft’s , which is available as a native 64‑bit component. This change meant that VBA now ran directly inside the 64‑bit AutoCAD process, eliminating the performance bottleneck of cross‑process communication.
: As described earlier, avoid using ObjectID altogether. Use Handle properties and HandleToObject methods in your external automation code. Alternatively, consider running both the controlling application and AutoCAD as the same bitness (both 32‑bit or both 64‑bit).
To run, edit, or develop .dvb (Developer VBA) files within AutoCAD 2015.
To run the 64-bit VBA module, your system must meet the base requirements for AutoCAD 2015 64-bit : AutoCAD 2015 System Requirements - CADDManager Blog autocad 2015 vba module 64-bit
Select the specific installer designated for . The file name typically includes AutoCAD_2015_VBA_Enu_Win_64bit.exe (or your respective language code). 3. Run the Installation Close all running instances of AutoCAD 2015.
The AutoCAD 2015 VBA Module for 64-bit systems is an essential utility for organizations maintaining legacy automation workflows. It successfully bridges the gap between 32-bit legacy code and modern 64-bit hardware. However, it requires diligent management regarding API declarations and pointer types to prevent runtime errors. IT Managers and CAD Developers must recognize that while the module provides backward compatibility, it represents a deprecated technology path, and strategic planning for migration to .NET is imperative for long-term stability.
Despite careful migration, you may encounter issues. Here are the most frequently reported problems and their solutions. AutoCAD 2014 was a watershed release
Autodesk decoupled VBA from AutoCAD to encourage developers to migrate to more modern, secure, and robust programming environments, specifically AutoLISP, .NET (C# or VB.NET), and the ObjectARX SDK.
Are you trying to , or are you writing a new script from scratch?
Enables the VBA IDE (Integrated Development Environment), command line support for VBAIDE , VBALOAD , VBAMAN , and VBARUN . Why You Need the 64-bit VBA Module : As described earlier, avoid using ObjectID altogether
Launch AutoCAD 2015. Type VBAIDE into the command line and press Enter. If the Microsoft Visual Basic for Applications window opens, the module is successfully installed. Migration and Code Compatibility Challenges
: Assures the 64-bit compiler that the Declare statement is safe to execute.
AutoCAD 2015 features strict security options regarding executable code. If your macros fail to load silently, check your security settings.
Before installing, ensure that AutoCAD 2015 is fully installed and closed.
