Working with revisions
A resource structure is a hierarchy of item revisions. Item revisions allow you to capture the state of a component or the entire assembly at a specific point in time.
Resource Manager always saves resources using the Precise revision rule. When you open an assembly, you see exactly those revisions of components that were used at the time it was saved. For best results, you should always view resource assemblies using the Precise revision rule.
When creating a new resource revision, Resource Manager can automatically revise all resource assemblies containing this revision.
