You can drag objects directly into your model.
Procedure
Open a model.
Click the Governance resources folder in the Navigation bar.
Select an object.
Drag an object into your modeling area. You can also drag an object directly onto an object in the model.
If you drag an object onto an activity of a non-matching type, a message is displayed asking whether you want to change the activity type. You are asked whether the information should be saved (which allows you to undo this action) or not.
You have modeled an object using drag and drop.
