Let's imagine a plastic model. e.g. a sandwich box or a ketchup cap. These are individual parts (not assemblies) containing type hinges “living hinge”.
Therefore, there may be a need to show alternative position.
Do you know, that you can also show this item in part?
It is enough to create two configurations representing individual positions and indicate them from the drawing level during defining Alternative position viewj.

The difference in relation to the assembly is about this, that in folds the configuration of an alternative position can be created only when the surgery is defined. In parts, the configuration should be prepared before.
