Файл IAM

Files with the .iam extension are used by the 3D modelling software Autodesk Inventor.

What are the contents of .iam files?

.iam files are created by Autodesk Inventor for storing assemblies - collections of components called parts and sub-assemblies. An .iam file does not embed part geometry directly; instead it holds references (file links) to the individual .ipt part files that make up the assembly, together with data defining the position of each component and its mechanical relations to other components (for example, alignment of mounting screws, bearing fits, and mating faces). Autodesk Inventor allows users to design or modify assemblies saved in .iam files. In this way a user can break a module down into its individual parts and reuse those parts in a new project. Users can also expand sub-assemblies, reposition components, or add new parts to an existing assembly.

Because an .iam file is a container of references rather than a self-contained model, moving or renaming any referenced .ipt file breaks the assembly. To share a complete assembly as a portable package, use Inventor's Pack and Go feature (which gathers all referenced files) or export to a neutral format such as a STEP file.

What are .iam files used for?

Autodesk Inventor is a professional program for creating parametric 3D models of mechanical designs. The assembly environment provided by .iam files not only lets users position modules within a complete design, but also lets them define assembly-level parameters such as joint constraints and motion relationships. Saving designed assemblies in .iam files facilitates component reuse and module-based design across multiple projects.

.iam files use the Microsoft OLE2 Compound File Binary container - the same structured-storage format used by other Inventor file types such as .idw drawings and .ipn presentation files. The format is proprietary and version-specific: assemblies saved by a newer Inventor release cannot be reliably opened by an older version.
