When you add a reference to Autodesk.Inventor.Interop.dll in your .NET project (Visual Studio), you gain access to the namespace. This namespace is the root of everything. 1. Inventor.Application

At its core, Autodesk.Inventor.Interop.dll is an . Because Autodesk Inventor is fundamentally written in C++ (a native language), its underlying COM (Component Object Model) API cannot be read directly by modern .NET languages.

Automatically exporting hundreds of IAM (Assembly) or IPT (Part) files to neutral formats like STEP, IGES, or PDF. autodesk.inventor.interop.dll

If your add-in must support Inventor 2022, 2023, and 2024, do reference a single autodesk.inventor.interop.dll . Instead:

The DLL is typically installed alongside Inventor in the following directory:

Microsoft .NET uses a system called COM Interop to bridge this gap. The Autodesk.Inventor.Interop.dll acts as a wrapper. It translates .NET commands into native COM commands that Inventor understands, and vice versa. : Once referenced, developers can use the Object

A solution for this, as recommended by Autodesk forum experts, is to reference the version of the DLL stored in the Windows Global Assembly Cache (GAC). The GAC stores multiple versions of the DLL side-by-side, allowing your application to be more resilient to minor version differences. Targeting the GAC location helps ensure your add-in remains compatible with a wider range of Inventor updates.

: It provides full read and write access to Inventor's data types, including parts ( ), assemblies ( ), and drawings ( Version Sensitivity The DLL is typically located in

If you are looking to start developing, you should look into creating an using the Inventor Add-in Wizard for Visual Studio.

Her chest tightened. That DLL name was familiar — it connected the Inventor application to outside code, the bridge plugins and scripts used to automate repetitive tasks. Without it, several in-house tools and the macro that populated custom properties would remain stubbornly silent.

Simply put, is a Runtime Callable Wrapper (RCW) . Inventor’s core API is written in native COM (Component Object Model). To allow .NET languages (C#, VB.NET) to talk to that COM interface, Visual Studio generates an interop assembly. This DLL acts as a bridge, marshaling calls between managed (.NET) and unmanaged (Inventor) code.
