The door is oriented the wrong way, but you'll fix that next.
When you copy doors from one opening to another, often the orientation
doesn't match. The best strategy is to use the hinge point as a point of reference
and place the door where it needs to go, as you just did. Then flip or rotate the
door so that it sits and swings the right way. The flipping of an object is known
as mirroring .
Mirroring objects
You have located the door in the opening, but it needs to be rotated 90º to be
perpendicular to the wall and then flipped so that it swings to the inside of the
bathroom. To do this, you'll use the ROTATE command that you used earlier, and
then the MIRROR command.
The MIRROR command allows you to flip objects around an axis called the
mirror line . You define this imaginary line by designating two points on the
line. Strategic selection of the mirror line ensures the accuracy of the mirroring
action, so it's critical to visualize where the proper line lies. Sometimes you'll
have to draw a guideline in order to designate one or both of the endpoints.
You can use the
ZOOM command
while you are in the
middle of using the
COPY command.
You can use most
of the display com-
mands ( ZOOM , PAN ,
and so on) in this
way. this is called
using a command
transparently .
1. Continue using 04A-FPLAY4.dwg , or open it if it's not already open.
2. Click the Rotate button found on the Home tab  ➢ Modify panel, and
select the door and swing for the bathroom door. With the door and
swing selected, press .
3. Activate the Endpoint osnap by entering END and then picking the
hinge point from the Specify base point: prompt.
4. At the Specify rotation angle: prompt, enter 90 .
The door is rotated 90º but its orientation is incorrect, as shown in
Figure 4.54.
5. Start the MIRROR command from the Home tab  ➢ Modify panel  ➢
Mirror tool button. Select the bathroom door and swing and press . The
prompt line changes to read Specify first point of mirror line: .
6. Activate the Endpoint osnap, and then pick the hinge point of the door.
The prompt changes to read Specify second point of mirror
line: , and you'll see the mirrored image of the door and the swing
moving as you move the cursor around the drawing area. You're
rotating the mirror line about the hinge point as you move the cur-
sor. As the mirror line rotates, the orientation of the mirrored image
changes (see Figure 4.55).
You can also start
the Mirror command
by entering MI .
