How to use Perspective guides

At present, only SketchBook for Desktop has these tools

There are four types of perspective guides.

1 point mode 1 point mode

Create an image with one vanishing point and a horizon. Draw images that appear as if you are viewing them head, such as looking down a street, train tracks, hallway, or at a building. Mouse over it to show the horizon (blue line). Drag to reposition the vanishing point and horizon.

Example of 1 point mode

2 point mode 2 point mode

Create an image with two vanishing points and a horizon. Draw images of an object with a corner facing you, such as the corner of a building. The walls will recede to the vanishing points.

Example of 2 point mode

3 point mode 3 point mode

Create an image with three vanishing points and a horizon. Draw images of an object that you are viewing from either above or below. When you mouse over or drag a vanishing point, a horizon line (blue) and triangle connecting the three points (light blue) appears.

Example of 3 point mode

In this video, we take you through a process of building a cityscape sketch in 3-point perspective, from start to finish.

Fisheye mode Fisheye mode

Create a panoramic or hemispherical image with a very wide angle of view. Draw images of a scene viewed from a convex mirror or lens.

Fisheye mode example
This mode has 5 vanishing points: left, right, top, bottom, and center. The grid is composited of a horizon line, vertical line, and circle. Curves intersect at the vanishing points. Moving the center point moves the entire grid. Moving an edge point changes the circle’s radius.

Perspective guides in SketchBook for Desktop

SketchBook Perspective toolbar labelled
Tap Perspective icon to access the Perspective tools and use these guides to help draw objects and scenes in perspective.

When you select a guide, notice how the cursor changes. Its display provides the directional options for any drawn lines.

For example, when using the Fisheye guide, the cursor looks like this:

The cursor for the 3 point guide looks like this:

Perspective tools

Use the following tools to aid with drawing:

Snap/Unsnap  Snap/Unsnap – When enabled, strokes will be straight and constrained to the horizon or vanishing points. When disabled, they will be freeform, with no constraints.

Lock/Unlock vanishing points Lock/Unlock vanishing points – When enabled, the vanishing points are locked into place and cannot be moved. When disabled, they can be repositioned.

Show/Hide horizon line Show/Hide horizon line – When enabled, horizon lines are visible. When disabled, it is not visible.

Notes for when saving perspective sketches

Setting Preferences > General > Default Save Format to:

  • TIFF maintains the last location of the perspective guide
  • PSD removes the perspective guide location

Moving vanishing points

To move a vanishing point, tap move a vanishing point lock/unlock to unlock the vanishing points and click-drag them into position.
Tap move a vanishing point unlock again to lock the vanishing points in place.

Hiding the horizon line

To hide the horizon line, tap Hiding the horizon line to hide it. Tap Unhiding the horizon line to display it.
