Isometric projection is the most commonly used axonometric projection, where the object is oriented such that the angles between each of the three principal axes (X, Y, and Z) are equal, typically at 120 degrees.
In this configuration, all three axes are scaled equally, making it straightforward to measure and draw the object. The equal scaling results in a drawing where the object’s dimensions along each axis can be accurately represented without any distortion. This uniformity makes isometric projection especially popular in engineering and technical illustrations, where the goal is to convey the shape and proportions of an object clearly.
