It can often be useful to merge changes to a model into another model particularly when working in a repository or on a design imported from another modeling tool.
To show the Merge models dialog:

1. Select the model-version you have made changes to in the tree and select  Merge into other model (where <model> is the model type) from the Worflow pane.
2. Select the model you want to merge your changes into and click OK.

   

3. The Merge models dialog is displayed.
