18 Machine Trades Print Reading Copyright Goodheart-Willcox Co., Inc. It is important to be able to visualize and understand the basic shape of objects before reading other reference material on the print. If you do not understand the objects shown, you will not understand the reference material. A misunderstanding can cause costly mistakes in the manufacturing process. A Multiview Application By applying the procedures of orthographic projection to the L-shaped object shown in Figure 2-13, you will create a multiview drawing. First, rotate the object into the front view position (in the same fl at plane as paper). Note, as the front view is drawn, the width is not seen. See Figure 2-14. Next, extend the projectors toward the top and right side view positions. Extend the projectors as far as needed between each view. Then, locate the top view and right side views by transferring the width dimension. Use a 45°miter angle to transfer the width from top to right side view, as shown in Figure 2-15. This unit covered the basic method of visualizing a multiview drawing. The drawing problems on the following pages allow you to practice your skills while increasing your understanding of multiview drawings. Goodheart-Willcox Publisher A pictorial view of a basic L-shaped object with the three primary views and basic dimensions labeled. Figure 2-13 The L-shape is not a practical machining project because most of the workpiece would be machined away in forming the L. However, the L-shape does lend itself well as a visualization exercise. PRO TIP
