Diagramming tools

The right side of the toolbar above the drawing palette provides all of the tools you need to build and modify your system under test. The following table lists the tools and their usage.

	Adds a new external resource to the diagram, launching a wizard that you can use to select the resource type and helps import it
	Creates a dependency (from an operation) to a component or operation
	Provides options to toggle the display of dependencies, clear all dependency filters, or edit dependency filters
	Enables the "select" cursor, which is the default cursor, for selecting, moving, and editing diagram items
	Increases the zoom of the current view (zoom in)
	Decreases the zoom of the current view (zoom out)
	You can draw a box around a specific area in the palette and zoom the view to that area
	Resets the current view to the default zoom
	Zooms the current view so that all diagram items fit on the screen
	Enables the "pan" cursor that you can use to grab a spot in the diagram and drag it around to change the view
	Organizes the contents of the palette
	Toggles the drawing grid (when enabled, items snap to the grid when created or moved)
