What's on your layers? In AutoCAD, users can utilize the LAYER WALK command, or LAYWALK. Lynn Alan has posted a video on her CADalyst Website, Lynn Alen's Tips and Tricks Tuesdays, that talks about the laywalk command.
Laywalk used to be an Express Tool, meaning that you had to purchase the express tools add on to get it. It also meant that AutoCAD LT users couldn't get it. Now it is a standard AutoCAD command and is available to both "vanilla" AutoCAD and AutoCAD LT.
Type in LAYWALK in the command line to start it. A window comes up listing all of the layers in your file. Pick one and all items on that layer will be displayed. If a layer is blank, nothing will show up. If nothing shows up, there is a button to purge that layer.
Watch the video to get a visual on how it works.
