Adjusting an Isometric Perspective Drawing Guide

The Isometric Perspective guide helps you draw lines that are parallel to one of three axes: the x-axis, the y-axis and the z-axis. By default, the z-axis is at 26.565° from the horizon, the x-axis is at 153.435° from the horizon, and the y-axis is at 90° from the horizon.

These specific angles are commonly used in video games and computer generated graphics, as lines in these angles do not require antialiasing to be properly rendered in pixels. The angle of all three of these axes can be adjusted independently as needed. For example:

• You can achieve "true" isometric perspective, where the angle between each axis is equal, by setting the angle of the x-axis to -150° and the angle of the z-axis to -30°.

• You can achieve cabinet-type oblique projection by setting the angle of the x-axis to -180°.

• You can achieve military-type oblique projection by setting the angle of the x-axis to -135° and the angle of the z-axis to -45°.
