Select Objects by Properties
Use object properties or object types to include objects in a selection set, or
to exclude them.
To quickly define a selection set based on specified filtering criteria, use
Quick Select (QSELECT) from the Properties palette to filter selection sets
by property (such as color) and by object type
Object Selection Filters dialog box (FILTER) to filter selection sets by
property and by object type
Select Similar (SELECTSIMILAR) to select similar objects of the same type
based on specified matching properties
If you added a feature classification to an object using Autodesk or a third-party
application, you can select objects by classification property. With object
selection filters, you can name and save filters for future use.
With Quick Select or object selection filters, to filter your selection set based
on color, linetype, or lineweight, 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.
By default, objects of the same type are considered similar if they are on the
same layer, and, for blocks and other referenced objects, have the same name.
