See Figure 3B-1. This supplement focuses on tools and drawing aids that help you create 2D isometric views that look 3D, as if the object tilts toward you. However, a 3D model provides a better way to display isometric views, for most applications. AutoCAD and Its Applications— Advanced describes how to construct 3D models. Figure 3B-1.
