Review questions
1 . There are three preset grids. Briefly describe what each could be used for.
2 . How can you show or hide the perspective grid?
3 . Before drawing content on a grid plane, what must be done to ensure that the ob-
ject is on the correct grid plane?
4 . What does double-clicking a grid plane control allow you to do?
5 . How do you move an object perpendicular to the grid?

Review answers
1 . The three preset grids are: one-point perspective, two-point perspective, and three-
point perspective. A one-point perspective can be very useful for roads, railway
tracks, or buildings viewed so that the front is directly facing the viewer. Two-
point perspective is useful for drawing a cube, such as a building, or for two roads
going off into the distance, and it typically has two vanishing points. Three-point
perspective is usually used for buildings seen from above or below. In addition to
vanishing points for each wall, there is a vanishing point in three-point perspective
showing those walls receding into the ground or high in space.
2 . You can show the perspective grid by selecting the Perspective Grid tool ( ) in
the Tools panel, by choosing View > Perspective Grid > Show Grid, or by pressing
Command+Shift+I (Mac OS) or Ctrl+Shift+I (Windows). To hide the grid, choose
View > Perspective Grid > Hide Grid, press Command+Shift+I (Mac OS) or
Ctrl+Shift+I (Windows), or press the Escape key with the Perspective Selection or
Perspective Grid tools selected.
3 . The correct grid plane must be selected by choosing it in the Plane Switching Wid-
get. You can select it by using the following keyboard commands: Left Grid(1),
Horizontal Grid(2), Right Grid(3), or No Active Grid(4); or by selecting content on
the grid you want to choose with the Perspective Selection tool ( ).

4 . Double-clicking a grid plane control allows you to move the plane. You can speci-
fy whether to move the content associated with the plane and whether to copy the
content as the plane moves.
5 . To move an object perpendicular to the grid, with the Perspective Selection tool,
hold down the number 5 key and drag the object perpendicular to the plane.
