What is the difference between Drawing Options and System Options?
System Options are a data base of customizable settings such as Wall Definitions which are used to
create the Drawing Options when you create a drawing. Any changes or updates done to the System Options will only
be implemented on future drawings. Any settings which are intended to be used on future drawings should be modified
here. Drawings Options are created at the time of starting a drawing, and any changes made to the Drawing Options
affect only the current drawing.
