The program internally computes base and final grid surfaces
from drawing geometry. The base surface is calculated from a
3D polyline representing the perimeter of the area being
analyzed. If that 3D polyline is drawn on the PERIMETER
layer, the command will automatically detect and use it. If
no 3D polyline is found on that layer, you have an opportunity to
manually select another 3D polyline to use. The 3D polyline
perimeter can be drawn with the Draw 3D Polyline Perimeter command
before using this routine.
The 3D polyline perimeter is also used as the inclusion perimeter for the volume calculation.
Additional 3D polylines can also be specified to more precisely
define the base surface. These must be on the BASE_BREAKLINE
layer to be used for this purpose. These can be generated by
the Draw 3DPoly Base Breakline routine.
The final surface is calculated from all of the other selected
drawing entities such as points, line, inserts, and polylines,
along with the perimeter polyline, but not including the
BASE_BREAKLINE polylines.
You have the option of setting the resolution of the grids.
