Layers

Layers are a method of managing the visual layout of a drawing. With the use of layers you can group or separate the objects of the current project according to various aspects. Layers can be turned on and off, and can be unlocked and locked. With the help of these commands you can group the objects of the different layers. The program can handle a total of 32767 layers.
