Autocad 2015 Vba Module 64-bit

To confirm the VBA module is active in your 64-bit environment:

If these commands are recognized, the 64-bit module is working correctly.

With the release of AutoCAD 2015, Autodesk continued the architectural shift from 32-bit to 64-bit computing environments. A significant consequence of this shift was the decoupling of Visual Basic for Applications (VBA) from the core installation package. This paper provides a detailed technical analysis of the AutoCAD 2015 VBA Module for 64-bit systems. It explores the architectural necessity of the module, the installation process, the critical migration challenges regarding API pointer safety, and best practices for legacy code maintenance. autocad 2015 vba module 64-bit

Starting with AutoCAD 2010, Autodesk began phasing out VBA due to security concerns and the rise of more modern APIs like .NET (C#/VB.NET) and AutoCAD's native AutoLISP. However, recognizing the massive library of legacy VBA macros in the industry, Autodesk continued to support VBA as a free add-on module.

For AutoCAD 2015 64-bit, there is no built-in VBA IDE. If you attempt to run a VBA macro (e.g., using the VBARUN command) or open a .DVB project file, you will receive an error stating that VBA is not installed. To confirm the VBA module is active in

Wrap all API Declare statements in the #If VBA7 block as shown above. Also, ensure you have #If Win64 to catch 64-bit-specific pointer logic.

#If Win64 Then
    ' Specific 64-bit memory handling
    Dim ptr As LongLong
#Else
    Dim ptr As Long
#End If

In the VBA IDE (Launch with VBAIDE), go to Tools → References. Check for "MISSING" references. Common missing references in 64-bit: If these commands are recognized, the 64-bit module

One advantage of the AutoCAD 2015 VBA Module 64-bit is memory. 32-bit VBA was limited to ~2GB of address space (or ~3GB with /3GB switch). 64-bit VBA has access to all the RAM on your machine.

To leverage this:

Autodesk has officially designated VBA as a "Legacy" technology. While the module is available for AutoCAD 2015, no new features are being added to the VBA API.
