Area Field Duplication (Tip #2105) comes from Jeff White. Start by creating a field linked to the area property of a polyline object in a drawing. Load the LISP code sent by Jeff and type AF at the Command line when you want to duplicate the area field for another polyline. Select the field object as a master (the command SM allows you select a new master), and then locate a different polyline that needs an area field. This function reduces the work when you need to have multiple areas in a drawing represented as field objects. A very nice and clean approach was used in the coding of this macro, making it not only useful, but a great example for learning more.
