Controlling layers from the command line. Can be a real shortcut when dealing with files that have a consistent layering convention and a large number of layers.

Type in “-la” at the command line

You are then given the following list of options.

Enter an option
[?/Make/Set/New/Rename/ON/OFF/Color/Ltype/LWeight/MATerial/Plot/Freeze/Thaw/LOck/Unlock/stAte/Description/rEconcile]:

For example to Thaw all the layers in the drawing

Type in “T” or “Thaw”

You are then prompted for the name of the layer or layers to select.

Enter name list of layers (s) to thaw

So for example you could type in “*” this acts as a wildcard and will select all the layers in the current drawing

Or

Type in "*$01*" this time the star symbol will ignore everything before and after the $01 so that any layer with the characters $01 within the layer name will be selected.

So then you can control your drawings layers from your keyboard rather than wading through the layer dialog box with the curser.
