Select the Command First
When you use an editing command, a Select Objects prompt is displayed and
the crosshairs is replaced with a pickbox. You can respond to the Select Objects
prompt in various ways:
■ Select objects one at a time.
■ Click an empty area. Drag the cursor to define a rectangular selection area.
■ Enter a selection option. Enter ? to display all selection options.
■ Combine selection methods. For example, to select most of the objects in
the drawing area, select all objects and then remove the objects that you
do not want selected.
■ Enter 'filter to use a named selection filter. The apostrophe runs the
command transparently.
Select Objects First
You can use one of two methods to select objects before starting a command:
■ Use the SELECT command, and enter ? to display all selection options. All
objects selected are put into the Previous selection set. To use the Previous
selection set, enter p at the Select Objects prompt of any subsequent
command.
■ When noun/verb selection is turned on, select objects at the Command
prompt before entering a command such as MOVE, COPY, or ERASE. With
this method, you can only select objects by clicking them individually or
by using automatic selection.
■ Enter qselect to filter the selection. Then enter p at the Select Objects
prompt of any subsequent command.
Highlight Objects to Be Selected
Objects are highlighted when the pickbox cursor rolls over them, providing
a preview of which object will be selected when you click. When you specify
an area to select multiple objects, the background of the area becomes
transparent.
These selection previewing effects are turned on by default. You can turn them
off with the SELECTIONPREVIEW system variable. When the PICKBOX system
variable is set to 0, selection previewing of objects is not available.
