four horizontal lines because the crossing selection box enclosed only one end-
point of each.
The STRETCH command takes some practice, but it's worth the effort. Draw some addi-
tional kinds of objects and practice stretching with different crossing selection box loca-
tions as well as different base points and second points.
The STRETCH command prompt says Select objects to stretch by
crossing-window or crossing-polygon but picking points as in Step 4
doesn't give you the crossing-polygon option. (See Chapter 10 if you need a re-
fresher on crossing-polygon selection.) To use a polygonal crossing selection, type
CP at the Select objects prompt and press Enter.
More Manipulations
The commands in this section — MIRROR, ROTATE, SCALE, ARRAY, and OFFSET —
provide other ways (in addition to MOVE, COPY, and STRETCH) of manipulating objects
or creating new versions of them. The procedures for each command assume that
you're familiar with the object selection and editing precision techniques presented in
the MOVE, COPY, and STRETCH procedures (see Chapter 10 and the previous sections
in this chapter).
Mirror
The MIRROR command creates a reverse copy of one or more objects. After you select
your objects, AutoCAD prompts you to select two points that define a line about which
the objects will be mirrored. You then have the option to retain or delete the source ob-
jects. Follow these steps to use the MIRROR command:
1. Press Esc to make sure that no command is active and no objects are selected.
2. Click the Mirror button on the Home tab's Modify panel.
3. Select one or more objects, and then press Enter to end object selection.
AutoCAD prompts you to define the mirror line by picking points:
