I use is so often I’ve lost count of how often I use this each day. This tool is designed to select all the objects that meet the chosen criteria. The tool has saved settings so that you can save the most frequently used settings for quick access. For example, you might want to select all the walls in your file, so set the criteria to select objects by Type. However, you might want to select object by the type and class, so that you only select the exterior walls.
