Select Objects by Properties
Bottom of the Page

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

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. 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.

NoteIf 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.
