Autodesk.inventor.interop.dll | 2027 |

is the primary dynamic-link library (DLL) that enables external software applications to communicate with and automate Autodesk Inventor. It serves as a Component Object Model (COM) Interop assembly, acts as a bridge between managed .NET code (like C# or VB.NET) and the unmanaged C++ source architecture of the Autodesk Inventor API.

You must add a reference to the Autodesk.Inventor.Interop.dll in your Visual Studio project to access the Inventor API . autodesk.inventor.interop.dll

You can connect to an already running instance of Inventor using COM methods, often facilitated by the Interop library. is the primary dynamic-link library (DLL) that enables

The Interop.dll acts as a wrapper, translating .NET code into COM calls that Inventor understands. It defines the namespaces, classes, interfaces, and methods available in the Inventor API. You can connect to an already running instance

is a critical dynamic-link library (DLL) file that serves as the bridge between external applications (such as .NET languages like C# or VB.NET) and the Autodesk Inventor COM-based Application Programming Interface (API). For engineers, CAD managers, and software developers looking to automate repetitive design tasks, extend Inventor’s functionality, or integrate Inventor with other systems (like ERP or PDM), understanding this library is the first step toward advanced customization.

: If the library doesn't appear in the standard COM tab in Visual Studio, you can manually browse to: C:\Program Files\Autodesk\Inventor [Version]\Bin\Public Assemblies\Autodesk.Inventor.Interop.dll [5.13, 5.16].
