Place Drillholes generates drillholes in the drawing that are required by the modeling routines. Each drillhole consists of an optional description(s), a surface elevation, and strata. Every strata has a name, bottom elevation, thickness, and optional attribute values and optional bed name. This the manual drillhole entry routine. If the holes are in a file already, then they may be imported with other import routines.
The prompting in Place Drillholes depends on the drillhole configuration file which is created by Define Drillhole. The first step is to select the drillhole configuration file (you only need to do it once, the file name will be remembered for the further use). Then specify the X and Y location of the drillhole followed by the surface elevation and drillhole description. If drillhole definition includes additional descriptions you will be prompted for values, these values are optional, so you may press Enter to continue. After entering this drillhole header information, a loop for entering the strata from top to bottom begins. If an undefined strata name is entered, there is an option to define that strata from there (see Define Strata for more on strata definitions). When all the strata are entered, enter a blank strata name to end the loop, or just hit Enter. This draws the drillhole in the drawing as an INSERT entity in the current DRILLHOLE layer with all the data attached. From there, another drillhole can be entered or the routine can be exited by pressing Enter. At any time in this routine, entering 'Undo' backs up the prompting sequence. The drillhole type is default to unknown with corresponding symbol used in the drawing. The symbols are defined in Define Drillhole and drillhole type may be changed in Edit Drillhole and Drillhole Data Sheet.
File Selection Dialog
Choose a drillhole configuration file.
Enter or Pick Drillhole x,y location (Enter to End):
5000,5000
Enter Drillhole surface elevation ('U' to Undo):
890.3
Enter Drillhole description ('Undo' to Undo): CH-11
This field is optional.
From here begins a loop to enter the strata in top to bottom
order.
Enter strata name (Enter to End, 'Undo' to Undo):
OV
Strata OV is a Non-Key strata. OV was found in the strata
definitions as a Non-Key strata.
Enter bottom elevation of OV ('U' to Undo): 883.7
Now enter the Non-Key attribute values for the attributes defined
by Define Drillhole.
Enter value for OV attribute ACID ('U' to Undo):
1
Enter value for OV attribute BASE ('U' to Undo):
2
Enter strata name (Enter to End, 'Undo' to Undo):
C
Strata C is undefined? Define now (<Yes>/No)?
No Defining strata C is optional.
Is C a Key or Non-Key strata (Key/<Non-Key>/Undo)?
Key All must be set as either Key or Non-Key.
Enter bottom elevation of C ('U' to Undo): 879.7
Now enter the Key attribute values.
Enter value for C attribute BTU ('U' to Undo):
10000
Enter strata name (Enter to End, 'Undo' to Undo): press
Enter if C is the last strata in the drillhole. Otherwise enter
the next strata name.
Enter or Pick Drillhole x,y location (Enter to End):
press Enter to exit Or specify another location for the next
drillhole.
