To use the file in your programming projects, follow these steps: Open your project in .

The end.

You can often use a DLL from an older version (e.g., 2018) to maintain compatibility with newer versions of Inventor.

(Note: Replace with your specific version of Inventor, such as 2024, 2025, or 2026). How to Use the DLL in Visual Studio autodesk.inventor.interop.dll

System.Runtime.InteropServices.Marshal.ReleaseComObject(partDoc); GC.Collect(); GC.WaitForPendingFinalizers();

When you add autodesk.inventor.interop.dll as a reference in your Visual Studio project, the .NET Common Language Runtime (CLR) generates Runtime Callable Wrappers (RCWs). These wrappers manage the activation of Inventor objects, marshal data back and forth, and handle memory cleanup. Where to Find the DLL

✅ generating drawings from parametric models.

This legacy error appears when you reference an older interop DLL built against .NET 2.0 while your project targets .NET 4.x or newer. If you are looking to start developing, you

Automating the generation of sketches, extrusions, fillets, and complex surfaces. Assembly Manipulation:

Found within Part and Assembly documents; this is where you modify geometry or parameters. Parameters: Allows you to read and write dimensions programmatically. 5. Troubleshooting & Tips Version Compatibility:

The is a critical component for developers looking to automate, extend, or integrate with Autodesk Inventor. It acts as the primary bridge—or interop assembly —between the .NET framework and Inventor's underlying Component Object Model (COM). To use the file in your programming projects,

If your code runs strictly inside Inventor, consider using iLogic or building an Inventor Add-In rather than an external EXE file. Internal tools execute faster because they do not have to communicate across different process boundaries. Propose Next Steps
