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 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.
Subobjects are only considered at the object level. For example, when a mesh
vertex is selected, SELECTSIMILAR selects other mesh objects, not just the
mesh vertices.
NOTE If an application such as AutoCAD
®
Map 3D was used to add a feature
classification to an object, and the associated classification (XML) file is present,
you can select objects by classification property. Specifically, you can select a
classification in the Object Type box and a property in the Properties box.
