Build custom property panels, ribbon buttons, and dialog boxes directly inside the Inventor user interface. Where to Find the File
: Set to True to ensure the specific version of the DLL is bundled with your compiled application.
: 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]. autodesk.inventor.interop.dll
Lesson 3: A First Look at Code for my First Inventor Plug-In
The Autodesk.Inventor.Interop.dll is the primary that allows .NET-based applications (like C# or VB.NET) to communicate with the Autodesk Inventor COM-based API. It acts as a bridge, translating managed .NET calls into the unmanaged COM commands that the Inventor software understands. Core Technical Concepts
: In newer Visual Studio versions, it may not appear in the standard COM reference list; you must manually Browse to the Public Assemblies folder to add it. Different version of Autodesk.Inventor.Interop.dll | Issue | Likely Cause | Quick Fix
The most common scenario. You create a Class Library project in C# or VB.NET, add a reference to autodesk.inventor.interop.dll , and implement ApplicationAddInServer interface. The DLL allows your managed code to respond to Inventor events, create UI panels, and manipulate geometry.
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.
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 | Set "Copy Local" = True for all references
: Usually set to False to avoid issues with event handling and specific COM types.
The is a critical component for developers looking to automate, extend, or integrate with Autodesk Inventor. It acts as the primary bridge—or interop assembly —between the .NET framework and Inventor's underlying Component Object Model (COM).
