Calculates the area and perimeter of objects or of defined areas.
Summary
Several commands are available to provide area information including AREA,
MEASUREGEOM on page 1122, and MASSPROP on page 1083. Alternatively, use
BOUNDARY on page 264 to create a closed polyline or region. Then use LIST
on page 1058 or the Properties palette on page 1545 to find the area.
List of Prompts
The following prompts are displayed.
Specify first corner point on page 142 or [Object on page 143/Add Area on page
143/
Subtract Area on page 144] <Object>: Select an option
The area and perimeter of the specified object displays at the Command prompt
and in the tooltip.
Specify Corner Points
Calculates the area and perimeter defined by specified points. All points must
lie in a plane parallel to the XY plane of the current user coordinate system
(UCS).
A rubberband line from the first specified point to the cursor is displayed.
Once the second point is specified, a line segment and a polygon with green
fill are displayed.
Continue to specify points to define a polygon and then press ENTER to
complete the definition of the perimeter. The area to be calculated is
highlighted in green.
If you do not close the polygon, the area is calculated as if a line were drawn
from the last point entered to the first. When the perimeter is calculated, that
line length is added.
