Object Measures the volume of an object or defined area.
You can select a 3D solids or 2D objects. If you select a 2D object you must
specify a height for that object.
If you define an object by specifying points, you must specify at least three
points to define a polygon. All must lie on a plane parallel to the XY plane of
the UCS. If you do not close the polygon, an area will be calculated as if a line
existed between the first and last points entered.

display.
Add Volume Turns on Add mode and keeps a running total of volume as you
define areas.
Subtract Volume Turns on Subtract mode and subtracts a specified volume
from the total volume.
Options for Selecting Polylines
You can select polylines when using the Distance, Area, and Volume options.
Arc Adds arc segments to the polyline.
Endpoint of Arc Draws an arc segment. The arc segment is tangent to the
previous segment of the polyline.
Angle Specifies the included angle of the arc segment from the start point.
Entering a positive number creates counterclockwise arc segments. Entering
a negative number creates clockwise arc segments.

Length Specifies the chord length of the arc segment. If the previous segment
is an arc, the new arc segment is drawn tangent to the previous arc segment.
Close Draws an arc segment from the last point specified to the starting point,
creating a closed polyline. At least two points must be specified to use this
option.
Direction Specifies a starting direction for the arc segment.
