what parts or products look like in parts manuals, repair manuals, and product catalogs.

Examples of isometric drawings are shown in Figure 16.9.

As was the case with orthographic views, there are specific rules that one must follow to

draw the isometric view of an object. We will use the object shown in Figure 16.10 to demon-

strate the steps that you need to follow to draw the isometric view of an object.

Step 1: Draw the width, height, and the depth axes, as shown in Figure 16.11(a). Note that the

isometric grid consists of the width and the depth axes; they form a 30angle with a

horizontal line. Also note that the height axis makes a 90angle with a horizontal line and

a 60angle with each of the depth and width axes.

Step 2: Measure and draw the total width, height, and depth of the object. Hence, draw lines

1– 2, 1– 3, and 1– 4 as shown in Figure 16.11(b).
