Select Multiple Objects

May 20, 2011

You can select multiple objects at one time using rectangular area or fence.

Specify a Rectangular Selection Area

You can select all objects inside the rectangular selection area. When specifying the first corner, there are two methods to define a rectangular selection window:

  • Drags the cursor from left to right to create a enclosed window selection. The objects entirely contained in the rectangular selection area are selected only.

  • Drags the cursor from right to left to create a crossing selection. The objects contained or passing through the rectangular selection area are selected.


The selected objects must be entirely contained in the window selection area when you use Window Selection. However, if the noncontinuous (dash) linetype is only partially visible in the viewport and all of the visible vectors of the linetype are inside of the selection window, the entire object is selected.


To create a Window

  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.

To create a Crossing Window

  2. Click to the left of the first point to select a second point in the drawing.

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 objects it crosses).


Specify an Irregularly Shaped Selection Area

You can select entities with an irregularly shaped area defined by the specified points. Under the prompt of SELECT command, you can select entities entirely enclosed by the selection area with the WPolygon, or the entities enclosed or crossed by the selection area with the CPolygon.

To select objects using Window Polygon

  1. Activate an object modification command.

  2. On the command line, type wpolygon.

  3. Specify the vertices of the polygon.

  4. To complete the selection polygon, press Enter.

Specify a Selection Fence

It could be much easier to select entities in a complex drawing by using a selection fence. A selection fence appears like a polyline and chooses only the entities it passes through.

To select objects using Fence

  1. Activate an object modification command.

  2. On the command line, type fence.

  3. Specify the endpoints of the Fence segments.

  4. To complete the Fence, press Enter.

Use Other Selection Options

Typing SELECT and entering ? displays all selection options, from which, you can choose a proper one.

Remove Selection from Multiple Objects

Under the prompt of Select entities, you can type R and choose a selection to remove objects from the selection set. You also can enter A to add objects to the selection set.

Holding down SHIFT and selecting objects again, the selected objects would be removed from the selection set.
