This document defines terminology used in isometric projection drawings. It discusses isometric axes, lines, planes, scales, and views. It then provides examples of how to construct isometric views of common 3D shapes like squares, rectangles, triangles, pentagons, hexagons, circles, prisms, pyramids, cones, cylinders, and spheres. Key steps include enclosing shapes in rectangles or squares, using isometric scales, and constructing shapes made of lines parallel or perpendicular to isometric axes.
