'DDSELECT Command

Sets object selection modes

	Tools menu: Selection
	Command line:ddselect

The Object Selection Settings dialog box is displayed.

DDSELECT controls the settings for object selection modes, pickbox size, and object sorting criteria for overlapping objects.

Selection Modes

Sets the selection mode. Select any combination of the options.

Noun/Verb Selection

With Noun/Verb selection on, you can select objects before entering a command. This setting is stored in the PICKFIRST system variable. If either GRIPS or Noun/Verb Selection is enabled, the graphics cursor changes to a combination of the pickbox and crosshairs.

You can use the following commands to edit objects with Noun/Verb Selection:

ARRAY	DDMODIFY	MOVE
BLOCK	DVIEW	ROTATE
CHANGE	ERASE	SCALE
CHPROP	EXPLODE	STRETCH
COPY	LIST	WBLOCK
DDCHPROP	MIRROR

Use Shift to Add

Controls how you add objects to a selection set. With this option turned on, hold down SHIFT to add more objects to the selection set. If you do not hold down SHIFT when selecting an object, you will overwrite the old selection set rather than adding to it. This setting is stored in the PICKADD system variable.

To clear a selection set quickly, draw a selection window in a blank area of the drawing. If Use Shift to Add is cleared, objects are added to the selection set as you select them. In either case, to remove objects, hold down SHIFT while selecting them again.

Press and Drag

Controls how you draw a selection window or crossing window. This setting is stored in the PICKDRAG system variable. With this option turned on, hold down the pick button and drag the cursor diagonally to create a selection window. Release the button to complete the window's opposite corner.

If Press and Drag is cleared, two separate points are required to define the selection window.

Implied Windowing

Creates a selection window. With this option turned on, you pick the first corner point in an empty area of the screen and AutoCAD LT prompts for the other corner point. Specifying the selection window from left to right selects objects that are completely inside the window's boundaries. Drawing from right to left selects objects within and crossing the window's boundaries. If Implied Windowing is off, picking an empty area of the screen will not result in an automatic window or crossing selection. Instead, AutoCAD LT reports that no objects were found. You can override this selection setting by using the Window, Crossing, or Auto options at the Select options prompt. Implied windowing can also be set using the PICKAUTO system variable.

Default Selection Modes

Resets the selection modes to their default settings (Noun/Verb Selection and Implied Windowing turned on).

Pickbox Size (DDSELECT)

Adjusts the size of the pickbox using a slider bar. This setting is stored in the PICKBOX system variable.

Object Sort Method Dialog Box (DDSELECT)

Provides options for processing overlapping objects in the order in which they were created in the drawing. You can use these options if your drawing or application depends on the order in which objects were created. Selecting additional sorting methods can increase processing time, which is related to performance enhancements for object selection in large drawings.

• Object Selection. Causes objects that are selected with a windowing method to be placed in the selection set in reverse order from that in which they were created.
• Object Snap. Causes Object Snap mode to select objects in the order in which they were created, from last to first.
• Redraws. Causes REDRAW to draw objects in their order in the drawing database, from last to first.
• Slide Creation. Causes MSLIDE to draw objects in their order in the drawing database, from last to first.
• Regens. Causes REGEN to draw objects in their order in the drawing database, from last to first.
• Plotting. Causes PLOT to process objects in their order in the drawing database, from last to first.
• PostScript Output. Causes PSOUT to process objects in their order in the drawing database, from last to first.
