Handbook
CONCLUSION
This example illustrates a simple method
of
drawing a
uniform and professional looking illustration. We also moved
the drawing surface
about
the page to accommodate a larger
diagram.
A
Dimensional
Illustration
Another application for MacPaint
is
the physical dia-
gramming
of
some machine, tool,
or
like object. In this exam-
ple,
we
will
draw
an
ax with labeled dimensions.
The example will illustrate the use
of
size alterations
to
achieve
proper
proportions. We will also get further practice in
drawing a large figure by moving the drawing surface
about
the
page. The use
of
customized patterns will also
appear
here
along with a discussion
of
lettering methods to improve
presentability.
INSTRUCTIONS
We
will begin by creating the
ax
head. This will cover most
of
the drawing surface.
Rather
than
drawing the parts free-
hand,
we
will use portions
of
other shapes.
For the
upper
and
lower arcs,
we
will use a flat ellipse.
Draw
an
ellipse with the
proper
arc.
Then
copy it
and
move the
copy vertically below the first as shown in figure 7.28.
If
the arc
is
not correct, you can adjust its size with the selection rectangle
and the sizing function.
Now, cut off the top portion
of
the upper ellipse and the
bottom
portion
of
the lower ellipse.
Then
create a long ellipse
to the right side
of
the drawing surface. The left
and
right arcs
of
the ellipse should be
appropriate
for the cutting edge
of
the
ax. Erase the right half
of
the ellipse.
Then
select it
and
move a
copy
of
it away from the original using the lasso. Position the
copy
at
the left edges
of
the first two arcs. Select the original
of
the long ellipse
and
flip it horizontally. As with the first, place it
at
the right edges
of
the first two arcs as shown in figure 7.29.
