Autodesk.inventor.interop.dll Jun 2026

Because Inventor was originally built using COM technology, .NET applications cannot interact with it directly. The Interop DLL acts as a "wrapper," translating .NET object calls into COM calls that Inventor understands. Key Characteristics

Out-of-process automation tools that connect to a running session from outside.

Synchronizing Bill of Materials (BOM) data between Inventor assemblies and enterprise resource planning software.

: Usually set to False to avoid issues with event handling and specific COM types. autodesk.inventor.interop.dll

Aria took a breath and followed the methodical approach she used for design problems:

is the essential gateway. This Dynamic Link Library (DLL) serves as the primary bridge between the Inventor application and external programming environments like C# or VB.NET. What is an Interop Assembly?

: If your app fails on other machines, check that "Embed Interop Types" is set correctly in your project settings—setting it to "False" while setting "Copy Local" to "True" is often required for complex automation tasks [5.19]. Because Inventor was originally built using COM technology,

To start coding, you must add a reference to autodesk.inventor.interop.dll in your Visual Studio project. Open your project in Visual Studio.

Autodesk does guarantee binary compatibility of the interop assembly across different Inventor releases. An add-in compiled for Inventor 2022 using the 2022 interop DLL will likely crash or throw MissingMethodException when run on Inventor 2024.

To understand the purpose of Autodesk.Inventor.Interop.dll , it helps to understand how the Inventor API is built. Synchronizing Bill of Materials (BOM) data between Inventor

In your project's reference properties, set Embed Interop Types to False . This avoids type equivalence issues and ensures proper marshaling of COM interfaces.
