Before manipulating a model, your code must attach to an active thread of the Inventor process.

Explicitly release your COM references using marshal tools when exiting your tool: if (invApp != null) Marshal.ReleaseComObject(invApp); Use code with caution. Summary of Use Cases Development Type Description When to Choose Inventor Add-Ins In-process DLLs compiled with an .addin manifest file.

: It is the gateway for creating add-ins, automation scripts, and external tools that interact with Inventor documents, geometry, and metadata.

Open, create, modify, and save parts ( .ipt ), assemblies ( .iam ), and drawings ( .idw / .dwg ).

autodesk.inventor.interop.dll is the fundamental building block for any developer looking to extend the capabilities of Autodesk Inventor. By providing a managed interface to the underlying COM API, it opens up unlimited possibilities for automation, customization, and integration.

Autodesk Inventor is natively built using C++ and exposes its features to the outside world via COM interfaces. Modern Windows development, however, heavily relies on .NET languages like C# and VB.NET. Because .NET cannot communicate with COM directly, it requires an intermediary layer.

This represents the active, running instance of the Inventor desktop application. Through this object, developers handle top-level tasks like modifying window visibility, altering application-wide options, or tracking overall user selections. 2. The Documents Collection

You can connect to an already running instance of Inventor using COM methods, often facilitated by the Interop library.
