Autocad 2013 Vba Module 64-bit

Any Windows API functions declared via the Declare statement must include the PtrSafe attribute. This tells the 64-bit compiler that the statement is safe to execute.

Older VBA macros are a common vector for malware (e.g., the “AutoCAD ACAD.vlx” virus). With the 64-bit module, Autodesk introduced requirements. In AutoCAD 2013 SP2, macros must be digitally signed or the user must enable “Low security” (not recommended). Always sign your VBA projects using a code-signing certificate or the SelfCert.exe tool.

If you cannot get the working, or if your code is too complex to migrate, consider these alternatives: autocad 2013 vba module 64-bit

The transition from 32-bit to 64-bit computing environments marked a significant milestone in computer-aided design. With the release of AutoCAD 2013, Autodesk altered how it distributed the Visual Basic for Applications (VBA) engine.

Because VB.NET shares syntax rules with classic VBA, it provides a smooth migration path for CAD developers. Transitioning code blocks to a modern IDE like Visual Studio allows you to build compiled .dll plugins that run directly inside AutoCAD's 64-bit memory space without requiring external out-of-process helper engines. This shift improves script execution speeds, enhances data security, and ensures your drafting automation tools remain stable across future versions of Windows and AutoCAD.

On , LongPtr evaluates to a standard 32-bit Long .

A: Yes, but with caveats. The module was written for Windows 7/8. On Windows 10/11, you may need to enable .NET Framework 3.5 and install the latest VC++ runtimes. Many users report successful operation. With the 64-bit module, Autodesk introduced requirements

The 64-bit VBA module for AutoCAD 2013 runs as an out-of-process component. It operates in its own memory space separate from the main AutoCAD executable, communicating via an automation bridge. How to Install the AutoCAD 2013 VBA Module (64-Bit)

#If VBA7 Then ' Code for AutoCAD 2013 64-bit (VBA 7.1) Declare PtrSafe Function GetFrequency Lib "kernel32" (lpFrequency As Currency) As Long #Else ' Legacy code for 32-bit AutoCAD versions Declare Function GetFrequency Lib "kernel32" (lpFrequency As Currency) As Long #End If Use code with caution.
