Declare Function GetModuleHandle Lib "kernel32" (ByVal lpModuleName As String) As Long
Here’s a review of the AutoCAD 2015 VBA Module (64-bit) based on common user experiences and technical considerations.
Autodesk provides the VBA module as a free add-on. However, finding the correct version is critical. Using a VBA enabler from AutoCAD 2013 or 2014 may lead to instability or failure to load.
| Issue | Likely Fix |
|-------|-------------|
| VBAIDE unknown command | VBA enabler not installed |
| Compile error: PtrSafe not found | Using wrong Office VBA (need VBA 7.0+). AutoCAD 2015 includes it. |
| API declares crash AutoCAD | Replace Long → LongPtr + add PtrSafe |
| VBA project won't load | Unblock file (right-click → Properties → Unblock) | autocad 2015 vba module 64-bit
Before diving into the 64-bit module, you must understand Autodesk’s rationale. VBA relies heavily on ActiveX and COM interfaces. As Autodesk moved towards a more secure, multi-threaded, and 64-bit native environment, embedding VBA became a liability. Old 32-bit VBA code could cause memory access violations and crashes in a 64-bit host process.
Consequently, starting with AutoCAD 2010, Autodesk made VBA a separate, optional download. AutoCAD 2015 continues this tradition. The 64-bit version of AutoCAD 2015 requires a specifically compiled 64-bit VBA module (often referred to as the "VBA Enabler") to interact with the 64-bit acad.exe process.

Without this module, menus like "Tools → Macros → VBA Manager" will be grayed out or missing entirely.
AutoCAD 2015 does not include VBA by default. You must download and install it separately. Autodesk provides the VBA module as a free add-on
While the module enables the execution of most standard VBA macros, there are distinct limitations compared to the .NET API:
