Snapshots are available in fully resolved assemblies and lightweight assemblies.
Previously, snapshots were available only in Large Design Review mode. Snapshots in resolved and lightweight assemblies work the same way as in Large Design Review mode, with capabilities such as recording the view orientation of the assembly, recording hide/show state of components, and adding comments. You can view snapshots in Large Design Review, resolved, and lightweight modes, regardless of which mode they were created in.
If you view a snapshot in resolved or lightweight mode, the View Snapshots pop-up toolbar appears. Click Exit Snapshot on the pop-up toolbar to return to the display state that was active before you viewed the snapshot.
