Each level is capable of having default attributes assigned to it. When that level becomes the active level, then the system attributes are set to match the default attributes. The default attributes that can be assigned are Color, Pen, Line Style, and Line Width. Changing the attributes of the active level will also update the system attributes.

Levels inherit their default attributes from their parents. If a level does not have default attributes, and none of its parents have default attributes, then the system attributes will not be changed by making that level the active level.
