IAM

An IAM file is an assembly model created with Inventor CAD and engineering software by Autodesk.

The IAM format comprises parts and subassemblies linked through assembly relationships. A subassembly in an IAM file is a self-contained unit with its collection of parts.

The .iam extension of an Autodesk Inventor Assembly Data File can be viewed using the following software: Autodesk Inventor / Inventor View, and Spaceclaim Engineer software. Autodesk Viewer web application and Fusion 360 integrated CAD / CAM / CAE software environment can import and render an assembly model created with Inventor.

ASM

ASM (Solid Edge Assembly) is one of the data file types used by Solid Edge CAD software. The files with .asm extension contain 3D parts (.prt) which consist of assemblies. ASM by itself, does not contain geometric information – it stores only the rules for connecting parts.

ASM (Solid Edge Assembly) also has no connection with assembly language, though this also uses an .asm extension.

Among CAD applications that support ASM extension are PTC Creo and Autodesk Fusion 360.
