The layer tool is the rectangular icon with a capital
L
in the lower left corner.
The layer tool is used to organize the objects on an EER Diagram canvas. It is useful for grouping together similar objects. You may, for instance, use it to group all your views together.
Click the layer tool and use it to draw a rectangle on the canvas. Change to the standard mouse pointer tool and pick up any objects you would like to place on the newly created layer.
To change the size of a layer, first select it by clicking on it. When a layer is selected small rectangles appear at each corner and in the middle of each side. Adjust the size by dragging any one of these rectangles.
You can also make changes to a layer by selecting the layer and changing properties in the Properties panel. Using the Properties panel is the only way to change the name of a layer.
From the keyboard, use the L key to activate this tool. For more information about layers see Section 7.5.5, “Creating Layers”.
