What Is a Perspective Ruler?

Select the [Layer] menu > [Ruler/Frame] > [Create Perspective Ruler] to create a ruler for perspective drawing with up to three vanishing points.

 

One-point Perspective

A drawing technique where straight lines making up the target objects are drawn to converge on one vanishing point. This is used to emphasize depth, such as when drawing a long corridor seen from the front.

 

Two-point Perspective

A drawing technique with two vanishing points on the same horizon line. Here, straight lines of one of the pairs making up the target objects are drawn to converge on the right vanishing point while those of the other are drawn to converge on the left vanishing point. This is used to draw an object from an oblique angle.

 

Three-point Perspective

A drawing technique with two vanishing points on a horizon line and a third vanishing point either above or below the horizon line. The straight lines making up the target objects are drawn so that they converge on their respective vanishing points. This is used to draw a tall build­ing seen from below, for example.
