Places selected objects in the Previous selection set
Command entry: selectSelect objects: Use an object selection method
A small box, called the object selection target, replaces the crosshairs on the graphics cursor.

Objects must be selected in order to be processed. The Select Objects prompt occurs after many commands, including the SELECT command itself.
You can select objects individually with the pointing device, by drawing a selection window around them, by entering coordinates, or by using one of the selection methods listed below. These methods can be used to select objects regardless of the command that initiated the Select Objects prompt.
You can also press and hold the CTRL key to select original individual forms that are part of composite solids or vertices, edges, and faces on 3D solids. You can select one of these subobjects, or create a selection set of more than one subobject. Your selection set can include more than one type of subobject.
To view all options, enter ? at the command prompt.

Select objects: Specify a point or enter an option
Selects all objects completely inside a rectangle defined by two points. Specifying the corners from left to right creates a window selection. (Specifying the corners from right to left creates a crossing selection.)
Specify first corner: Specify a point (1)
Specify opposite corner: Specify a point (2)

Selects the most recently created visible object. The object must be in the current space, that is, model space or paper space, and its layer must not be set to frozen or off.
Selects objects within and crossing an area defined by two points. A crossing selection is displayed as dashed or otherwise highlighted to differentiate it from window selection. Specifying the corners from right to left creates a crossing selection. (Specifying the corners from left to right creates a window selection.)
First corner: Specify a point (1)
Other corner: Specify a point (2)

Selects all objects inside or crossing a rectangle specified by two points. If the rectangle's points are specified from right to left, Box is equivalent to Crossing. Otherwise, Box is equivalent to Window.
Specify first corner: Specify a point
Specify opposite corner: Specify a point
Selects all objects on thawed layers.

Selects all objects crossing a selection fence. The Fence method is similar to CPolygon except that that the fence is not closed, and a fence can cross itself. Fence is not affected by the PICKADD system variable.
First fence point: Specify a point
Specify endpoint of line or [Undo]: Specify a point or enter u to undo the last point

Selects objects completely inside a polygon defined by points. The polygon can be any shape but cannot cross or touch itself. The last segment of the polygon is drawn so that it is closed at all times. WPolygon is not affected by the PICKADD system variable.
First polygon point: Specify a point
Specify endpoint of line or [Undo]: Specify a point or enter u to undo the last point

Selects objects within and crossing a polygon defined by specifying points. The polygon can be any shape but cannot cross or touch itself. The last segment of the polygon is drawn so that it is closed at all times. CPolygon is not affected by the PICKADD system variable.
First polygon point: Specify a point
Specify endpoint of line or [Undo]: Specify a point or enter u to undo the last point

Selects all objects within a specified group.
Enter group name: Enter a name list
Switches to the Add method: selected objects can be added to the selection set by using any of the object selection methods. Auto and Add are the default methods.

Switches to the Remove method: objects can be removed from the current selection set using any object selection method. An alternative to Remove mode is to hold down SHIFT while selecting single objects or use the Automatic option.
Specifies multiple points without highlighting the objects, thus speeding up the selection process for complex objects. The Multiple method also selects two intersecting objects if the intersection point is specified twice.
Selects the most recent selection set. The Previous selection set is cleared by operations that delete objects from the drawing.
The program keeps track of whether each selection set was specified in model space or paper space. The Previous selection set is ignored if you switch spaces.
Cancels the selection of the object most recently added to the selection set.
Switches to automatic selection: pointing to an object selects the object. Pointing to a blank area inside or outside an object forms the first corner of a box defined by the Box method. Auto and Add are the default methods.
Switches to the Single method: selects the first object or set of objects designated rather than continuing to prompt for further selections.
Allows you to select original individual forms that are part of composite solids or vertices, edges, and faces on 3D solids. You can select one of these subobjects, or create a selection set of more than one subobject. Your selection set can include more than one type of subobject.
Select objects: Select original individual forms that are part of composite solids or vertices, edges, and faces
Pressing and holding the CTRL key is the same as selecting the SELECT command’s Subobject option.

Ends the ability to select subobjects. Allows you to use object selection methods.
