touches,
and
the masterpiece
is
complete. Refer back to figure
6.2 on page
166
for the finished product.
Constraints also apply
to
the irregular polygon shapes.
They follow the same guidelines as did the line. Any shape
whose angles are multiples
of
45
degrees can be created using
these constraints.
SPECIAL FUNCTIONS
The remaining special functions available with the key-
board are illustrated in figure 6.33. In this section
we
will
discuss these special functions
and
illustrate their uses.
The
Option key
is
used
to
copy a portion
of
the document.
We
will show this function by using the Option key
to
manipu-
late a copy
of
the kite
about
the page. First select the kite and
then press
and
hold the Option key. The selected portion
of
the
document will be copied as
soon
as
we
attempt
to
use the
pointer to move the selection.
Use the pointer
to
drag the
selection away from the original. This feature
is
quite useful
when repeated versions
of
a drawing are required.
To
create
another
copy, simply release the mouse, repress the button,
and
continue to
drag
the object. We will use this feature exten-
sively in the examples in the next chapter.
To create a copy which
is
aligned vertically
or
horizontally
with the original, use
Option
and
Shift together. An example
of
horizontally aligned copying
is
shown in figure 6.34.
