Model Differencer dialog - for Modeler CM
The Model Differencer dialog allows you to compare the differences between two different versions of a model, or the same model in different repositories.
The Model Differencer dialog is opened when you perform the following operations:
• From Model Explorer: When you right-click the model version, point to Difference, and then click With Original Trunk, With Latest Trunk, With Predecessor, With Selected Version, or With Other Model.
• From Modeler: When you click the Manage, and click With Other Model or click the arrow next to With Other Model, and then click With selected Version, With Latest Trunk, With Predecessor, With Original Trunk, or With Parent Branch.
In the Model Differencer dialog, you can expand items to locate the items that are different in each model. These entries are shown in Bold. In the columns for the models, the dialog shows you what the differences are.
You can navigate from one difference to another difference through the following toolbar buttons:
Navigate to Previous Difference
Navigate to Next Difference
For a branch (sandbox), the Model Differencer can compare the branch with both the latest version of the trunk, and the version of the trunk from which the branch was created (Difference > With Latest Trunk command).

The Model Differencer dialog has the following columns:
• Type - Shows the symbols of the item types shown in the Name column.
For links and properties, the type column is blank.

Reporting of differences
The columns for the model version show you what the differences are between the models. For example:
• 'Added' means that the item has been added to the model in that model version.
• 'Only Present in this model' means that the item appears in that model version, but not the other model version.
For links the columns show the items that are linked through that link in each model version.
For properties the columns show the value of the property in that model version.
