This command draws a 3D polyline in the BASE_BREAKLINE layer.
This polyline is used by the Calculate Stockpile Volume and
Calculate Pond/Pit Volume routines to model the base
surface. You may want to set your Object Snap prior to running this
routine so that you obtain the elevations of existing points while
creating the 3D polyline. Besides picking and entering the points,
you can also use point numbers from the current coordinate (.CRD)
file.
This routine functions identically to the Draw 3DPoly Perimeter command, only
placing the resulting 3D polyline on a different layer.
