But what happens when I need to put a wall on a wall-demo layer? Hmmm... Do I have to manually create that layer and use the change properties to change it? If you don't know about the Layer Key Overrides, then you are probably doing that manually.
ADT has a built in tool that few users are taking advantage of. The Layer Key overrides will allow you to temporarily override the layer that the objects are placed on. If I need to draw a wall on a wall-demo layer, all I have to do is to turn the layer key override on and set the status to Demo. As long as it is on, any object that I place will be put on a layer with a -demo extension to it. If I place a door, it will be put on a door-demo layer.
When I am finished drawing demo items, I simply turn the layer key override off and it's back to normal.
Layer Key Overrides - what a time saver. If you are not using them, check it out!
