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

(Steven Felgate) #1
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.
