After creating a plane in Vanishing Point, you can create (tear off) additional planes that share the same perspective. Once a second plane is torn off from the initial perspective plane, you can tear off additional planes from the second plane and so forth. You can tear off as many planes as you want. Although new planes tear off at 90° angles, you can adjust them to any angle. This is useful for making seamless edits between surfaces, matching the geometry of a complex scene. For example, corner cabinets in a kitchen can be part of a continuous surface. In addition to adjusting the angles of a related perspective plane, you can always resize the plane using the Edit Plane tool.
The bounding box and grid change colors to indicate the plane’s current condition. If your plane is invalid, move a corner node until the bounding box and grid are blue.
Select the Edit Plane or
the Create Plane
tool,
and then enter a Grid Size value in the tool options area.
(Photoshop Extended only) Select the Measure tool and
then select Link Measurements To Grid in the tool options area.
Drag the Measure tool in a plane and enter a Length value in the
tool options area.
