Engineering Fundamentals: An Introduction to Engineering, 4th ed.c

Step 3: Create the front, the top, and the side work faces. Draw line 2 –5 parallel to line 1– 3;

draw line 4 – 6 parallel to line 1– 3; draw line 3 –5 parallel to line 1– 2; draw line 3 – 6

parallel to line 1– 4; draw line 5 –7 parallel to line 3 – 6; and draw line 6 –7 parallel to line

3 –5 as shown in Figure 16.11(c).

Step 4: Complete the drawing as marked by the remaining line numbers, and remove the

unwanted lines 3 – 6, 3 – 8, 3 –12, 6 –13, and 6 – 9 as shown in Figure 16.11(d).

Next, we will use an example to demonstrate the steps in creating an isometric view of an

object.

Steps in creating an isometric

view: (1) Create the isometric

axes and grid; (2) mark the

height, width, and depth of the

object on the isometric grid;

(3) create the front, the top,

and the side work faces; and

(4) complete the drawing.
