Filtering Selection Sets in AutoCAD

Using either the Quick Select or Object Selection Filters dialog box, you can filter selection sets by property (such as color) and by object type. For example, you can select all of the red circles in a drawing without selecting any other object; or you can select all objects except the red circles.
With Quick Select, you can quickly define a selection set based on filtering criteria that you specify. With Object Selection Filters, you can name and save filters for future use.

With either method, if you want to filter your selection set based on color, linetype, or lineweight, first consider whether these properties are set to BYLAYER for any objects in your drawing. For example, an object may appear red because its color is set to BYLAYER, and the layer color is red. To create a filter recognizing this object, design the filter to look for objects that either exist on that layer or that have a color value of BYLAYER, not red. For information about assigning properties by layer, see “Working with Layers.”

For partially opened drawings, Quick Select does not consider objects that are not loaded.
Once you create a selection set, you can use the Object Properties toolbar or the Properties window to view or modify properties of the selected objects. For more information, see “Editing Object Properties.”
In the following example, you use Quick Select to select the red objects in a drawing.

To create a selection set using Quick Select

  1. From the Tools menu, choose Quick Select.
  2. In the Quick Select dialog box under Apply To, select Entire Drawing.

  5. Under Operator, select Equals.
  6. Under Value, select Red.

You can exclude objects from a current selection set by using the Exclude from New Selection Set option. In the following example, you exclude all circles with a radius greater than 1 from a set of objects already selected.

To exclude objects from the selection set

  1. On the Tools menu, choose Quick Select.
  2. In the Quick Select dialog box under Apply To, select Current Selection.
  3. nder Object Type, select Circle.
  4. Under Properties, select Radius.
  5. Under Operator, select Greater Than.
  6. Under Value, enter 1.
  7. Under How to Apply, select Exclude from New Selection Set.
  8. Choose OK.

AutoCAD removes all circles with a radius greater than 1 from the selection set and closes the Quick Select dialog box.

You can also use Quick Select to append objects to a current selection set. In the following example, you keep the current selection set and append all objects in the drawing that contain hyperlinks whose names begin with bld1_.

To append objects to the selection set

  1. On the Tools menu, choose Quick Select.
  2. In the Quick Select dialog box, select Append to Current Selection Set.
  3. Under Object Type, select Multiple.
  4. Under Properties, select Hyperlink.
  5. Under Operator, select *Wildcard Match.
  6. Under Value, enter bld1_*.

Related FILTER names and saves filters and provides options for more complex filtering.

To name and save a filtered list

  1. At the Command prompt, enter filter.
  2. In the Object Selection Filters dialog box under Select Filter, select Line.
  3. Choose Add to List.
  4. Under Save As, enter a filter name such as Linefilter.
  5. Choose Save As.
  6. Choose Apply.

AutoCAD applies the filter so you can select only lines in the drawing. If you select objects with a window, AutoCAD applies the filter to all objects in the window.

You can restore a saved selection set by selecting the filter name under Current in the Object Selection Filters dialog box.
