make than isometric drawings. Seasoned engineers can
interpret orthogonal drawings without needing an isometric
drawing, but this takes a bit of practice.
The top "outside" view of the bearing is shown in figure 6.7. It
is an orthogonal (perpendicular) projection. Notice the
direction of the arrows for the "A-A" cutting plane.

6.2. How Sections Are Shown
To clearly draw the sectional views, we have to understand
the following terminologies.
A. Cutting Plane Lines
The cutting plane line indicates the path that an imaginary
cutting plane follows to slice through an object. Think of the
