Chapter 12 Arranging and Patterning Objects
357
Array Option
Use the
Array
option of the
COPY
command, available after you specify the base
point, to create a linear pattern of the selected objects. AutoCAD includes other
ARRAY
commands, described later in this chapter, which are usually more appropriate for
patterning objects. However, the
Array
option of the
COPY
command is effective for
copying multiple, equally spaced objects quickly. Choose the
Array
option and then
enter the total number of copies, including the selected objects, to create. Specify the
location of the fi rst copy, which also defines fi the spacing between copies. An alternative fi
is to use the
Fit
option and then specify the location of the last copy, which divides the
number of items equally between the base point and second point. Figure 12-9 shows
an example of developing a pattern using the
Array
option of the
COPY
command.

Mirroring Objects Mirroring Object s
The
MIRROR
command allows you to reflect, or mirror, objects. For example, in fl
mechanical drafting, mirror a part to form the opposite component of a symmetrical
assembly. In architectural drafting, mirror a floor plan to create a duplex residence or fl
to accommodate a different site orientation. Access the
MIRROR
command and select
the objects to mirror. Then create an imaginary mirror line at any angle by specifying
two points. After you locate the second mirror line point, you have the option to delete
the original objects. See Figure 12-10.
NOTE N OT OT TE
The
MIRRTEXT
system variable, which is set to
0
by default, prevents text
from reversing during a mirror operation. Change the
MIRRTEXT
value
to
1
to mirror text in relation to the original object. See Figure 12-11.
Backward text is generally not acceptable, except for in applications
such as reverse imaging.
