Model and package symbols (CM tool integration)
In the Modeler panes, a Model's and Package's symbol changes to indicate its status.
Note that the configuration control symbols are shown only when the CM tool integration is enabled. You can enable and disable the CM tool integration through the Enable Configuration Management Integration check box for the General entry on the Tool Options dialog.
When under configuration control, a Model and Package icon can include a lock, pencil, outgoing arrow and incoming arrow:
means you do not have write access to the Model or Package.
means you do have write access to the Model or Package.
means the Model or Package is under configuration control and is checked out by you to the Modeler model.
means the Model or Package is under configuration control and is not checked out by you.
A Model or Package icon can appear as follows:
The Model or Package is not under configuration control.
You have write access to the Model or Package.
The Model or Package is not under configuration control.
You do not have write access to the Model or Package.
The Model or Package is under configuration control.
The Model or Package is checked out by you to the current Modeler Model.

The Model or Package is under configuration control.
The Model or Package is checked out by another user to the Modeler Model.
You have write access to the Model or Package.
The Model or Package is under configuration control.
The Model or Package is not checked out by you to the Model.
You do not have write access to the Model or Package. Note that a check in operation protects a Model or Package, so that no users of the Model will have write access to the Model or Package.
The Model or Package is under configuration control.
The Model or Package is checked out by you to the Modeler Model.
You do not have write access to the Model or Package.
This symbol displayed to the left of a Model or Package symbol indicates that the Model or Package is shared in the CM tool.
A short-cut symbol on an item's icon indicates that the item is a stub. Note that when the Model is a stub, the short-cut symbol is not used.

The arrows appear on Package and Model symbols only if you are a valid and licensed user of the integrated configuration management tool.
