will prompt fitst for  which is its current
angle and then will prompt for the . All is in
reference to the current UCS.  can also
be defined by an object already in the drawing using ,
, etc. tools.

This command changes the scale of the user selected
objects by a user defined value.

This command allows the user to remove (erase) portions
of object that cross a user specified boundary. AutoCAD
will prompt you to . This command can be very deceptive in
3D. What appears to intersect may not and the cursor may
not be where you think it is.

CREATI GTHE SOUND PLOT
1. Start with  and the tirle of the drawing with the
scenic design for the production that you are going to use.
2. Scan the  through the pulldown menu . Look for layers that you can remove because they
are no longer needed for a sound plot. Also check for untirled blocks. Enter  and then . This command
sequence will list the use of blocks.
3. Use  to create your sound plot drawing. At the
prompt enter the tirle for your drawing and then enter.
Don't work in the master file that you have been provided
and don't hesitate to create temporary work files when in
doubt. It is easier to delete unwanted files than it is to
recover files.
4.  your sound plot drawing. Before AutoCAD will
open the new drawing it will prompt as to whether to , , or . Select . This will save the master file.
5. Once the new drawing is opened at the prompt enter
. To  all unreferenced object at the prompt
enter  and reboot AutoCAD. Reopen your soundplot
drawing and enter  again. This operation may have
to be repeated several times to remove all unreferenced
enaaes.
6. Remove unwanted layers. Use the pulldown menu and .  those layers that you
wish to keep and turn  those layers that you wish to
keep. Be sure to keep layer o. Enter  and use 
 (crossings) and remove all unwanted information.
Reenter  and  and  those
layers left that you need. Then enter .

7. Since the primary focus for your drawing is the sound
information, you need to set pen weights appropriately for
the other layers. For example, you probably want to keep
the set but you need to remove unwanted information
(e.g., scenic text, scenic detail, etc.) and you need to assign
them a pen weight of lesser value since the focus of this
drawing is sound and the set is just there to reference placement. Use  to change the color/pew weights. You
might also want to check layer by layer through 
 to make sure that all remaining objects are
in the correct layers. You can use   to move
objects berween layers. AutoCAD will prompt you to
