You can select all objects in a drawing that have the same object type, style, and layer as one or more preselected objects. If the objects selected are of different types, the selection is based on shared properties.
For example, you can select all walls in the drawing that use the CMU-Rigid style and are placed on the A-Walls layer.
Note: Block references are selected based on their layer and block definition. Style-based objects are selected on their style.
- Select the object on which to base the preselection criteria.

All objects that match the type, style, and layer of the object are added to the selection set. You can now make changes to the selection set, for example on the Properties palette.
