This command draws a 3D polyline in the PERIMETER layer. This
is one way to generate the polyline that is required by
the Calculate Stockpile Volume and Calculate Pond/Pit
Volume routines. In these routines, this polyline is used as the
inclusion perimeter for volumes. If you are using Carlson drawing
points to define the polyline, make sure they are present in the
drawing at their real Z elevation, and then set your AutoCAD
Object Snap to Insert prior to running this routine. Alternatively, you
can use point numbers from
the current coordinate (.CRD) file. A third option is to obtain
the elevations of picked points from a specified surface model.
Ignore Z values of picked points (.XY filter) [Yes/<No>]:
Y Using the .XY filter allows the user to pick the X and Y
coordinate
from the screen and type
in the elevation. If you use the N
response then the Z coordinate of
the point picked will be applied.
Use surface model from file
[<Yes>/No]? Y Select surface model file.
Number/<Pick point>: pick a point
Number/Close/Undo/<Pick point>:
N
Close/Undo/Pick point/<point Number>:
15 This is a
point number from the
current coordinate file.
Close/Undo/Pick point/<point Number>: press Enter Pressing
Enter ends the command.
