Modifying entities - Selecting entities

Entity-selection methods

When you choose a command that requires you to select entities (when you're deleting or changing entity properties, for example), you can use any of the following selection methods by choosing them in the prompt box or entering them in the command bar:

Select all entities (ALL) Selects all entities in the current drawing.

Add to set (+ or A) Adds one or more entities to the selection set.

Subtract from set (- or R) Removes one or more entities from the selection set.

Previous selection (P) Selects entities included in the previous selection set.

Last entity in drawing (L) Selects the entity most recently added to the drawing.

Window-Inside (W) Selects entities contained entirely within a rectangular selection window.

Crossing window (C) Selects entities contained within or crossing the boundary of a rectangular selection window.

Outside window (O) Selects entities falling completely outside a rectangular selection window.

Window polygon (WP) Selects entities contained entirely within a polygon selection window.

Crossing polygon (CP) Selects entities contained within or crossing the boundary of a polygon selection window.

Outside polygon (OP) Selects entities falling completely outside a polygon selection window.

Window circle (WC) Selects entities contained entirely within a circular selection window.

Crossing circle (CC) Selects entities contained within or crossing the boundary of a circular selection window.

Outside circle (OC) Selects entities falling completely outside a circular selection window.

Point (PO) Selects any closed entities that surround the selected point.

Fence Selects entities crossing a line or line segments.

Select by Properties (PRO) Selects entities that match a particular set of proper-ties--for example, all entities on a particular layer or drawn in a certain color.
  1. You can also use a few selection methods automatically, without displaying the prompt box. For example, you can simply click to select entities, or you can use a Window-Inside or Crossing Window by defining the opposite corners of a rectangular selection window. The direction in which you define the points of the rectangle (left-to-right or right-to-left) determines which type of window you create.
To create a Window-Inside
  1. Click to select a point in the drawing.
  2. Click to the right of the first point to select a second point in the drawing.
  3.

  1. This method is most commonly referred to as simply a window or selection window.
To create a Crossing Window
  1. Click to select a point in the drawing.
  2. Click to the left of the first point to select a second point in the drawing.
  3.

  4. In addition to a rectangular window, you can define a selection window using other shapes such as a polygon, circle, or fence (a multisegmented line that selects entities it crosses).
To select entities using Window Polygon
  1. Activate an entity-modification command.
  2. In the prompt box, choose Window Polygon.
  3. Specify the vertices of the polygon.
  4. To complete the selection polygon, press Enter.

To select entities using Fence
  1. Activate an entity-modification command.
  2. In the prompt box, choose Fence.
  3. Specify the endpoints of the Fence segments.
