About perspective planes and the grid
Before you can make edits in Vanishing Point, you define rectangular planes that line up with the perspective in an
image. The accuracy of the plane determines whether any edits or adjustments are properly scaled and oriented in your
image.
After you establish the four corner nodes, the perspective plane is active and displays a bounding box and a grid. You
can scale, move, or reshape to fine-tune the perspective plane. You can also change the grid size so it lines up with
elements in the image. Sometimes, lining up the bounding box and grid with a texture or pattern in your image helps
you accurately match the image’s perspective. Adjusting the grid size can also make it easier for you to count items in
the image.
Besides helping to line up the perspective planes with image elements, the grid is helpful for visualizing measurements
when used with the Measure tool. An option is available to link the grid size to measurements you make with the
Measure tool.

Define and adjust perspective planes in Vanishing Point
1
In the Vanishing Point dialog box, select the Create Plane tool
and click in the preview image to add the four
corner nodes.
Try to use a rectangular object or a plane area in the image as a guide when creating the perspective plane. To help with
node placement, hold down the “x” key to zoom into the preview image. As you add corner nodes, you can delete the
last node if it’s not correct by pressing the Backspace key (Windows) or Delete key (Mac
OS). You can also reposition
a node by dragging it.

Select the Edit Plane tool
and do one or more of the following:
•
To reshape the perspective plane, drag a corner node.
•
To adjust the grid, enter a value in the Grid Size text box or click the down arrow and move the slider. You can also
adjust the grid size when the Create Plane tool is selected.
•
To move the plane, click inside the plane and drag.
•
To scale the plane, drag an edge node in a segment of the bounding box.
