Using View Controls

View controls are used to manipulate a view, the portion of the design displayed in a view window. The most commonly used view controls can be selected in the View Control Bar docked to the top of each view window .

Some of the most useful view controls include the following:

The Update View view control is provided to redraw the display when an operation leaves a view with an incomplete display. For example, if you delete an element that crosses in front of (and partially obscures) another element, the part of the underlying element that should be revealed might not be redrawn automatically.
Window Area , which is used to define a smaller area to display in the selected view, or another.
Fit View , which is used to fit the entire model in a view (for the "big picture" or to get your bearings).
Rotate View , which is used to rotate a view.
View Previous , which is used like an Undo function to negate previous viewing operations, as many as eight per view.

View Controls and Workflow

View controls operate much like drawing tools; many even have "tool" settings.

The interaction between view controls and tools results in an intuitive, comfortable workflow:

When you select a view control, it becomes active immediately. Any drawing operation in progress is suspended.
When you finish using a view control, control returns to the selected drawing tool, thereby letting you continue the drawing operation from the point at which it was suspended.

Locating and Selecting View Controls

View controls are located as follows:

By default, the view control bar, which contains the most commonly used view controls, is docked by default to the top of each view window.
The Tools ribbon group in the View tab of the ribbon.
In any case, view controls are located in the View Control toolbox. The procedure for locating a view control in a toolbox is the same as that for locating a tool in a toolbox.

Note: The operation of the selected view control depends on the manner in which it is selected.

If you select a view control from a particular view's view control bar, you also are selecting that view as the one on which to operate.
If you select a view control from a toolbox, the tool will apply to the active view, which is the one with the highlighted title bar. You can make a view the active view by entering a data point within it, clicking its title bar, starting a tool from the view's control bar, or right-clicking within it.
