Autodesk Inventor File Types

Autodesk Inventor File Types

Unlike AutoCAD and Mechanical Desktop, which maintain one file with multiple types of data, Autodesk Inventor maintains data in multiple associated files.

3D part model data is contained in a file with the extension .ipt.
3D assembly model data is contained in a file with the extension .iam.
2D drawing data is contained in a file with the extension .idw, .dwg.
Autodesk Inventor also maintains presentation files (.ipn) that contain definitions for exploded assemblies and specialized assembly views.
