To view the default two-point perspective grid in a document, you can do any of the following:
Click View > Perspective Grid > Show Grid.
Press Ctrl+Shift+I (on Windows) or Cmd+Shift+I (on Mac) to show the Perspective Grid. The same keyboard shortcut can be used to hide the visible grid.
Click the Perspective Grid tool from the Tools panel.

The Perspective Grid tool group consists of the Perspective Grid tool and the Perspective Selection tool .
You can select the Perspective Grid tool from the Tools panel or press Shift+P. When the Perspective Grid tool is selected, it shows:
Left and right grid controls to adjust planes (see Adjust vanishing points, grid planes, horizon height, grid cell size, and grid extent)
Horizon height (see Precise perpendicular movement)
Left and right vertical plane position
Visibility and extent of a grid cell
Grid cell size
Left and right ground level widgets used for grid movement (see Move the perspective grid)
In addition, when you select the Perspective Grid, a Plane Switching Widget also appears. You can use this widget to select the active grid plane. In Perspective Grid, an active plane is the plane on which you draw an object to project the observer’s view of that portion of the scene.

You can set options to position the widget on any of the four screen corners and choose to display it when the Perspective Grid is visible. To set these options, double-click the Perspective Grid icon in the Tools panel. In the Perspective Grid Options dialog box, you can select the following:
Show Active Plane Widget
This option is selected by default. If you deselect this check box, then the widget is not displayed with the Perspective Grid.
You can choose to display the widget on the upper left, upper-right, lower-left, or lower-right corner of the document window.
When you select the Perspective Selection tool, the left, right, and horizontal grid controls are displayed. You can switch to the Perspective Selection tool by pressing Shift+V or selecting it from the Tools panel. The Perspective Selection tool enables you to:
Bring objects, texts, and symbols in perspective
Switch active planes using keyboard shortcuts
Move, scale, and duplicate objects in perspective space
Move and duplicate objects perpendicular to its current position in the perspective plane. (see Precise perpendicular movement)
With the Perspective Selection tool, the active planes in the perspective grid are indicated by the following pointers.
The Perspective Selection tool snaps the objects to the grid of the active plane while moving, scaling, duplicating, and bringing objects into perspective. Objects snap to the grid lines within 1/4th distance of the cell size.
You can enable or disable snapping from View > Perspective Grid > Snap to Grid.
This option is enabled by default.
