Creating Perspective Rulers

  1. Select Layer β†’ New Layer β†’ Perspective Ruler

  2. Choose perspective type:

    • 1-Point - Single vanishing point (hallways, roads)

    • 2-Point - Two vanishing points (buildings, boxes)

    • 3-Point - Three vanishing points (extreme angles)

Using the Ruler

Once created:

  1. Your brush strokes snap to perspective lines

  2. Drag vanishing points to adjust

  3. Use with any brush tool

Vanishing Point Controls

  • Click and drag to move vanishing points

  • Hold Shift for constrained movement

  • Right-click for options menu

Tips

  • Place vanishing points off-canvas for subtle perspective

  • Use 2-point for most architectural work

  • 3-point creates dramatic bird’s eye or worm’s eye views

Tip

Create the ruler on a separate layer so you can hide it when not needed.
