1. Volume calculation above/below 3D_Faces surface
   (command: volume)
--------------------------------------------------
3D Faces must be drawn before using this command.
When the command is executed, AutoCAD will prompt you to open data file,
the results of the calculation will be written to.
The second step you'll be asked, select wheter you want to calculate
the volume in all locality or you'd like to select some Faces only.
Then you have to input the datum height (altitude).
All results (area, surface, volume) will be written to the text file.


Example of the file:


	Volume calcul below / above 3D faces

	(center coordinates YXZ - area - surface - prism volume)

	Triangles :  3
	Datum     :  100.0

	1       173.333   163.333   102    4800   4802.05   9600
	2       246.667   129.667   103.333    11790   11796.69   39300
	3       346.667   179.667   105    7860   7864.46   39300

	Area of the locality           [m2] :  24450
	Surface of the locality        [m2] :  24463.2
	Volume above(+)/below(-) datum [m3] :  88200
