If you don't want a layer to show up in your final prints, then there is an option for that as well on the LAYER PROPERTIES MANAGER palette. Click on the Plot icon next to the name of the layer. The Plot icon will also now show a rounded red cross and the layer will become a no-plot layer, meaning objects on the layer will no longer show when printed even though they will still show up in the drawing area:

The Defpoints layer that we saw in earlier examples is set to "no plot" by default, and you can't change it back to a "plot" layer. Besides the standard the LAYER PROPERTIES MANAGER palette, you can also control the layer status using the Layers panel, which is a quicker way of managing layer status in drawings containing tens or hundreds of layers. We will discuss these quick access tools in the next section.
