first since it will be used as an axis of
revolution.

These centerlines are used to ensure
symmetry of the section.

Use
, , and (Fillet Tool) to draw the section as shown below. Then use
to dimension the section, and use to modify the dimensions so that the
resulted section is shown below.

lines as shown, and
dimension the distance
between them to 5.25
mm.







Draw a
horizontal
centerline
through the
center of the
