Define an Area
You can measure an arbitrary closed region defined by the points you specify.
The points must lie on a plane parallel to the XY plane of the current UCS.
Calculate the Area, Perimeter, or Circumference of an Object
You can calculate the enclosed area and perimeter or circumference of circles,
ellipses, polylines, polygons, regions, and AutoCAD 3D solids. The information
displayed depends on the type of object selected:
Circles. Area and circumference display.
Ellipses, closed polylines, polygons, planar closed spline curves, and regions.
Area and perimeter display. For wide polylines, this area is defined by the
center of the width.
Open objects such as open spline curves and open polylines. Area and
length display. Area is calculated as though a straight line connects the
start point and endpoint.
AutoCAD 3D solids. Total 3D area for the object displays.
