Laywalk is one of those commands that began life as an Express Tool, but now is available as a command in both AutoCAD and AutoCAD LT. Laywalk lets you view the objects that reside on each layer in your drawing. This can be handy when you have a drawing in which objects are not on the correct layers. Before you start moving objects around, save the layer state and export it to an external text file, in case something goes horribly wrong.
To start Laywalk, type Laywalk at the command prompt. You can also access it via the Format menu, under Layer Tools. Or on the Layers II toolbar. Or on the Layers panel of the Ribbon’s Home tab. If you have an older version of AutoCAD, access it through the Express Tools menu.
A dialog box appears, listing all of the layers in your drawing. Select a layer in the list, all of the objects on that layer are displayed. If the layer is empty, nothing will appear, and Laywalk will display a button so you can purge that layer, if you wish. Note that the number of layers in the drawing is displayed in the title bar. Note also that you can select multiple layers by dragging or using the Shift or Ctrl key.

When you check the Filter box at top right, the list displays only those layers that match the active filter. When the Filter box is not checked, all layers are displayed. The filter box is enabled only when there is an active filter.
Right-click on a layer name to bring up more options.
Hold Selection turns on the Always Show option for selected layers. Release Selection turns it off. You can also double-click a layer name in the list to turn Always Show on and off. An asterisk will appear to the left of each layer that is held.
Select All selects and displays all layers, and Clear All clears all layers. Invert Selection clears all currently selected layers and selects all that aren’t selected. Select Unferenced selects all unreferenced layers. If you choose this option, the Purge button at bottom left becomes live.
You also can save the current selection of layers as a layer state. The Restore on Exit checkbox at the bottom returns layers to their previous state when you close the Laywalk dialog box. When the box is not checked, AutoCAD saves any changes you made.
