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.
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.
Control the Appearance of Selected Objects
By default, selected objects are displayed with dashed lines. You can increase
program performance by setting the HIGHLIGHT system variable to 0. Turning
off selection highlighting does not affect grips on selected objects.
Set Up Default Selection Methods
The default selection methods are:
Use selection previewing and selection area effects to preview selection.
Select objects before entering a command (noun-verb selection) or after
entering a command. (PICKFIRST)
Press Shift to append objects to the selection set. (PICKADD)
Click and drag to create a selection window. Otherwise you must click
twice to define the corners of a selection window. (PICKDRAG)
Start Window or Crossing selection automatically when you click an empty
space. Otherwise, you must enter c or w to specify window crossing
selection. (PICKAUTO)
