There is also some overlap with Positional Representations. They can do everything that Level of Detail does plus everything that iAssembles does.

Model States in assemblies can control parameters, constraints (including overrides and suppression), and be linked to model states. Simplification levels for removing intellectual property or high levels of detail before export.

Level of completion for each stage as your design as it gets assembled.

Alternative assembly positions for quickly switching between them visually or for defining drawing views.

Product families that have different values for dimensions or features that are shown or suppressed.

Weldments for weld preparation and other machining operations.

Sheet metal part in varying stages of completion for multiple bend operations.

Machining operations from the casted model to the final part.

Because the variations exist in one file, there is no need to worry about managing multiple files that represent the member variants or breaking the associations between those files. It is a mechanism for managing variations in parameters, properties, component suppression/substitution and physical simplification among other things. Model States is a powerful new workflow that enables users to create multiple representations of a part or assembly within a single document. Inventor 2022 introduces a new core technology called Model States.
