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 AutoCAD 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.
Prompt for elevations (.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 No response then the Z coordinate of
the point picked will be applied.
Use surface model from file
[<Yes>/No]: Y With this option, a surface file
is specified, and then with each screen pick, the surface elevation is
determined. If Prompt for elevations is set to No, the surface
elevation is applied to the polyline vertex. If set to Yes, the
surface elevation is displayed as the default, and can be accepted by
pressing Enter, or a different elevation can be typed in instead.
Pick point or point number: pick a point or type a point
number
Arc/Close/Undo/Pick point or point number: 15 This is a
point number from the
current coordinate (.CRD) file. Note that if the response to Use
Surface model from file is Yes, the elvation used it not the point
elevation from the coordinate file (.CRD), but the elevation
interpolated from the surface.
Arc/Close/Undo/Pick point or point
number: press Enter
Draw another 3D polyline [Yes/<No>]? press Enter Pressing
Enter ends the command.
