Use the 64-bit VBA module to keep your legacy macros running on modern workstations, but plan to rewrite critical routines in .NET or AutoLISP over time.
Autodesk officially phased out native VBA support starting with AutoCAD 2010. The company shifted its primary development focus toward the .NET framework and AutoLISP. However, due to the massive volume of legacy code used by enterprises, Autodesk continues to provide VBA as a separate, optional download.
: Replace any reference to ObjectID32 or direct ObjectID access with the object’s Handle property, which is a string that remains valid across both 32‑bit and 64‑bit environments.
If your office uses a mixed environment (some users on legacy 32-bit AutoCAD, others on 64-bit AutoCAD 2015), use conditional compilation constants to ensure the code runs everywhere: autocad 2015 vba module 64-bit
By mastering the 64‑bit VBA module in AutoCAD 2015, you can unlock the best possible performance for your existing VBA‑based workflows while building a foundation for the next generation of AutoCAD automation.
While VBA in AutoCAD 2015 64‑bit is a powerful tool, it is also a mature technology with a clear sunset on the horizon. Use this guide to get your existing macros up and running today, but also begin planning your transition to the AutoCAD .NET API for future‑proof automation and customization.
Without this module, attempting to run .dvb files or using commands like VBAIDE will result in errors. 2. Prerequisites for Installation Use the 64-bit VBA module to keep your

This guide covers everything you need to know about implementing the environment. Why AutoCAD 2015 Requires a Separate VBA Module
For teams looking to modernize their CAD automation, migrating to or C# via the AutoCAD ObjectARX .NET API is highly recommended. Visual Basic for Applications (VBA) .NET (C# / VB.NET) Execution Speed Moderate (Interpreted) Fast (Compiled) UI Capabilities Basic UserForms Advanced WPF and WinForms Security Low (Vulnerable macro files) High (Compiled DLLs / Digital Signatures) Architecture Requires separate Enabler Native out-of-the-box support
The represents a fundamental shift in how VBA operates within the AutoCAD ecosystem. By moving to a native 64‑bit VBA 7.1 engine, Autodesk delivered vastly improved performance for macros and custom tools, but this came at the cost of breaking backwards compatibility with many 32‑bit components.
If you type a VBA command and receive this error, the module is either missing, corrupted, or blocked by Windows User Account Control (UAC). Re-run the installer by right-clicking the setup file and choosing . 64-bit Compilation Errors (PtrSafe)
Because AutoCAD 2015 is an older release, finding the active download link on the Autodesk Knowledge Network can sometimes be challenging. Navigate to the official Autodesk support website.
