Determine Whether to Compare All or Compare Selected Objects

When you make your report selections on the Compare Options dialog, you will notice the Object Range option. This lets you specify whether to compare all objects in both models, or to compare aggregate objects you select from a selection list.

If you are using Version Control for the first time on a model, you can want to use the compare all objects option. The advantage of comparing All objects is that you can be sure the report will be comprehensive. For additional considerations, see the table, Comparing Advantages of All and Selected in Selecting the Object Range.

When using Compare All, it is not necessary to become familiar with aggregate object types before you run the report for the first time. It is reasonable to defer this until you begin analyzing the report results and planning the objects to select for the aggregate set to use for your next function. Then you can focus on only the aggregate object types you have in your model. For details on aggregate object types for Compare Report, see Become Familiar with Aggregate Object Types.
