Autodesk.inventor.interop.dll

autodesk.inventor.interop.dll is a Primary Interop Assembly (PIA) provided by Autodesk. It acts as a managed code wrapper around the native COM (Component Object Model) libraries of Autodesk Inventor.

This DLL allows developers to write .NET applications (in C# or VB.NET) that can communicate with, control, and automate Autodesk Inventor. Without this assembly, .NET code could not directly interpret the complex data types and object structures exposed by Inventor's COM API. autodesk.inventor.interop.dll

First, let's break down the name:

autodesk.inventor.interop.dll is a Runtime Callable Wrapper (RCW) assembly. Autodesk Inventor’s core Application Programming Interface (API) is written in native C++. However, most modern customizations and add-ins are written in .NET languages like C# or VB.NET. Native C++ and managed .NET code cannot talk to each other directly. The Interop DLL acts as a translator. autodesk

When you install Autodesk Inventor, this DLL is placed in the program's installation directory. Its sole purpose is to expose Inventor’s COM (Component Object Model) objects as .NET-friendly objects. For example, the native PartDocument COM interface becomes a managed class you can use in C#. let's break down the name:

Extract BOM (Bill of Materials), mass properties, or custom iProperties from Inventor files into Excel, SQL, or custom reports. The interop DLL gives you read/write access to document properties.
