Autocad 2015 Vba Module 64-bit _top_ May 2026
AutoCAD 2015 VBA Module (64-bit) is an optional "VBA Enabler" required to run Visual Basic for Applications macros within the 64-bit version of AutoCAD 2014 or later. Starting with the 2014 release, AutoCAD transitioned to the
engine, which runs as a native 64-bit process if the host AutoCAD software is 64-bit. Autodesk Community, Autodesk Forums, Autodesk Forum 1. Key Technical Changes 64-bit Native Process:
Unlike older versions (2013 and earlier), where VBA remained a 32-bit process even on 64-bit systems, the 2015 module runs natively in 64-bit. VBA 7.1 Engine:
This version is not 100% backward compatible with VB6. You may need to update legacy code, specifically when dealing with 32-bit Windows API calls 32-bit OCX controls , which are no longer supported in this environment. ObjectID Changes: 64-bit VBA uses 64-bit long integers for
. If you are automating AutoCAD from a 32-bit application like Excel, references to will likely cause crashes. Autodesk Community, Autodesk Forums, Autodesk Forum 2. Installation Guide
VBA is no longer included in the default AutoCAD installation media and must be added separately. Access the AutoCAD 2015 VBA Enabler 64-bit directly from Autodesk Support Preparation: Close all running programs, especially AutoCAD. Extraction: autocad 2015 vba module 64-bit
Double-click the downloaded EXE to unzip it to a local folder (typically C:\Autodesk Execution:
from the extracted folder and follow the on-screen prompts to complete the installation. Verification: Launch AutoCAD and type
at the command prompt. If the Visual Basic Editor opens, the module is correctly installed. 3. Common Compatibility Issues
The AutoCAD 2015 VBA Module (64-bit) is a critical specialized extension that enables users to automate repetitive tasks and extend the core functionality of AutoCAD using the Visual Basic for Applications (VBA) language. While traditionally included in earlier versions, it is now a separate "VBA Enabler" that must be downloaded and installed to match the specific 64-bit architecture of the host system. Purpose and Functionality
The module bridges the gap between AutoCAD’s design environment and the power of Microsoft Visual Basic. Key roles include: AutoCAD 2015 VBA Module (64-bit) is an optional
Automation: Creating macros to handle complex or repetitive drawing tasks that would otherwise require manual input.
ActiveX Integration: Using the AutoCAD ActiveX Automation Interface to communicate with drawing entities, data, and system commands.
Interoperability: Facilitating data exchange between AutoCAD and other 64-bit Windows applications like Excel or Access. Installation and Requirements
The 64-bit module is specifically designed for 64-bit workstations, which offer nearly unlimited RAM usage compared to legacy 32-bit systems. AutoCAD 2015 System Requirements - CADDManager Blog
Here’s a review of the AutoCAD 2015 VBA Module (64-bit) based on common user experiences and technical considerations. The Exact File You Need
The Exact File You Need
- Product: Autodesk AutoCAD 2015 VBA Module
- Architecture: 64-bit (x64)
- File Name:
AutoCAD_2015_VBA_Module_64bit.exe(or similar, depending on language pack) - Version: This module is specifically built against the ObjectDBX 2015 libraries.
Pros
- Essential for legacy workflows – If you rely on VBA macros from older AutoCAD versions (like 2008–2014), this module lets them run in AutoCAD 2015 64-bit.
- Familiar environment – Uses the standard VBA 7.1 IDE, similar to Office VBA, so no new language learning for existing users.
- Lightweight – Small download (~15–20 MB) and quick to install.
- COM interoperability – Still works well with Excel, Word, and other COM-enabled apps for data exchange.
- No additional cost – Free download from Autodesk (though requires valid AutoCAD 2015 license).
6. Functionality and Limitations
While the module enables the execution of most standard VBA macros, there are distinct limitations compared to the .NET API:
- Performance: Because of the interoperability layer between 64-bit AutoCAD and the VBA runtime, heavy computational macros may run slightly slower than natively compiled .NET extensions.
- UI Limitations: VBA forms (UserForms) in the 64-bit module do not support some of the advanced Windows Forms controls available in .NET. Additionally, ActiveX controls used on VBA forms must be 64-bit compliant; many legacy third-party ActiveX controls are 32-bit only and will fail to load.
- Security Macros: AutoCAD 2015 introduces stricter macro security. The
SECURELOADsystem variable restricts the loading of VBA projects from untrusted paths (network locations). Administrators must configure trusted locations to allow network-based macros to function.
Issue: The VBA IDE shows "Out of Memory" when editing a large form
Solution: This is a rare but known issue with the 64-bit VBA7 runtime. Workaround: Split your UserForm into multiple forms or move non-visual logic into standard modules.
The #If VBA7 Directive
To write code that works in both 32-bit and 64-bit VBA environments, you must use conditional compilation.
Example: Declaring a Windows API function to get the AutoCAD window handle
#If VBA7 Then
' 64-bit compatible declaration
Declare PtrSafe Function GetParent Lib "user32" (ByVal hWnd As LongPtr) As LongPtr
#Else
' Legacy 32-bit declaration
Declare Function GetParent Lib "user32" (ByVal hWnd As Long) As Long
#End If
Notice the PtrSafe keyword. This is mandatory for any Declare statement in 64-bit VBA. Without it, your module will throw a compile error.
Correct 64-bit version:
Declare PtrSafe Function GetModuleHandle Lib "kernel32" (ByVal lpModuleName As String) As LongPtr
Key changes:
PtrSafekeywordLongPtr(adapts to 32/64-bit) instead ofLongfor handles/pointersLongLongfor 64-bit integers (rarely needed)
Critical Technical Considerations for 64-Bit VBA
Simply installing the 64-bit module is not enough. Your old code written in a 32-bit environment (AutoCAD 2007 or earlier) will likely break. This is the most misunderstood aspect of the transition.
6. Alternatives (if VBA unsuitable)
- AutoLISP / Visual LISP – Native, no separate install
- .NET (C#/VB.NET) – More powerful for 64-bit, but steeper learning
- ObjectARX – C++ only, max performance
