Place Drillhole

Function

This command allows you to screen pick or enter coordinates the placement of a drillhole.

Go to Drillhole/Strata Settings, Place Drillhole Prompts, to determine how you would like to be prompted. When you select Place Drillhole from the Drillhole menu, the command line prompt shows:

"Pick Drillhole Location:"  Type in x-y coordinates or move your pointer around the screen to pick the placement of the drillhole.  If you are in Dialog Mode defined in Drillhole/Strata Settings, once a location was picked on the screen, the following dialog box appears:



Place DrillHoles generates drillholes in the drawing that are required to run strata surface application routines. Each drillhole consists of a surface elevation, strata, and optional description(s). Every strata has a name, bottom elevation, thickness. Within a drillhole, the strata names must be unique, but each real-world strata should have the same strata name across all the drillholes. This is because strata surface applications connects together the strata with the same name.

The drillhole data can be entered in the dialog shown here, or if Depth or Thickness Mode is selected under Drillhole/Strata Settings, then the data can be entered in on the command line when you place each drillhole. Make sure to specify the surface elevation and drillhole description. While in Dialog Mode or to change data, use the Edit and Insert/append buttons to enter strata data. The symbols are defined in DrillHole/Strata Settings and drillhole may be changed in Edit DrillHole. Pick Save when done and a drillhole symbol is drawn.

●  Edit:  Make changes to the highlighted strata name.  Thickness, Bottom Elevation, Depth.



When placing drillholes, every strata must be assigned a bottom elevation and a thickness. The bottom elevation is the elevation of the bottom of the strata. There are different methods for entering this information.

●  Adjust Bottom Elevations:  Will make adjustments to the bottom elevation based on thickness changes.

●  Adjust Next Thickness:  Will adjust the next thickness to hold the bottom elevation unchanged.
