space of the layout. These dimensions are
used to establish the width and height of
a centering rectangle within the drawing
area. For this example, the rectangle
measures 7-1/2″ × 5″. The three views
of the object will fi t inside this rectangle.
After completing the drawing, the views
will be centered horizontally and verti-
cally on the drawing sheet.
6. To draw the centering rectangle, divide
the width (7-1/2″) by 2. Mark points
for this measurement (3-3/4″) from
the center point on each side along the
horizontal construction line. Draw two
vertical construction lines through the
two measured points to create the sides
of the centering rectangle.
7. In similar fashion, divide the height of
the centering rectangle (5″) by 2. Mark
points for this measurement (2-1/2″)
from the center point on each side along
the vertical construction line. Draw two
horizontal construction lines through the
two measured points to create the top and
bottom of the centering rectangle.
8. Erase the diagonal construction lines used
for locating the center of the drawing
area. Also, erase the horizontal and
vertical construction lines intersecting the
center. These lines are no longer needed
and could be misidentifi as part of the fied
object drawing. After erasing these lines,
the centering rectangle can be used to
block in the views.
9. To complete the drawing, measure hori-
zontally from the lower-left corner of the
centering rectangle. Lay out the overall
width, the 1″ spacing between views, and ″
the depth of the object. See Figure 9-27.
Draw two vertical construction lines
through the two measured points and
extending the full height of the centering
rectangle. These are Lines A and B in
Figure 9-27E.
