Civil 3D: Adjust COGO Point Elevation (borehole , Pipe Network)

Automatic correction of COGO point elevation based on encoding data + additional data in the display.
This is convenient when shooting drilling, municipal utilities (to display the depth of Pipe Network).
We need to create a new Point File Format to import data:
When importing points, it is convenient to use the NAME in the format of PNEZDN points to display additional information in the label (depth of laying), where N is the Name.
To automatically change the point elevations, you need to reload the shooting points, but when importing, configure the following format PNEZZ- , where Z is a negative correction for the elevation.
(Z-: Include this column name to adjust the elevation of a point in a file. The value in the Z- column for a point can be subtracted from the value in the Elevation column when the points are imported or transferred.)
do not forget Select the Do Elevation Adjustment If Possible option when importing points
