Understanding Autodesk.Inventor.Interop.dll: The Gateway to Inventor API Automation
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.
Open, create, modify, and save parts ( .ipt ), assemblies ( .iam ), and drawings ( .idw / .dwg ). autodesk.inventor.interop.dll
Always reference the interop DLL from the specific Inventor version you're targeting. Do not copy it to another location manually—reference it directly from the Inventor install folder.
A very common point of confusion is the "Embed Interop Types" property. It is highly recommended, especially for add-ins that must handle events, to set this property to False . When set to True (the default in some older .NET project templates), the compiler embeds the interop types directly into your add-in. This can lead to complex and hard-to-debug errors, particularly with event handling. By setting it to False , your add-in relies on the external interop DLL, which often results in more stable and predictable behavior.

In the world of professional 3D mechanical design, stands as a powerhouse for parametric design, simulation, and visualization. However, the true potential of Inventor is unlocked when users move beyond the graphical user interface (GUI) and into the realm of API (Application Programming Interface) development . At the heart of this customization lies a crucial file: Autodesk.Inventor.Interop.dll .
