A brief explanation of isometric projections:
Isometric projections are a useful method for showing multiple views of an object to clearly represent even the most complex objects accurately. Isometric projections are used everyday as a method of communicating in sketches, technical drawings, and presentations. Isometric projection is defined as "a projection in which all three faces are equally inclined to the drawing surface so that all the edges are equally foreshortened."
