Interpolate range between
This is one of a number of functions which can used to interpolate and label new drill holes by selecting two existing drill holes. With this function you can select two existing drill holes (points) and enter a range to define both the number of holes which are to be created, and the values which are to be used for the numeric part of the hole ID. This function uses the hole ID formatting characteristics entered using the DEFINE HOLE ID FORMAT function to create the drill hole IDs.
To run this function: Choose Design > Grade control > Hole numbering options > Define range between numbered ends, or...
Note that this function does not label the selected end points so you must define at least one value in the range which you enter to permit interpolation to occur.
Select the first point
Position the cursor and select the point at which you want to start interpolating and labelling drill holes.
Select the point of interest to display the prompt:
Select the second point
Position the cursor and select the point at which you want to end interpolating and labelling drill holes.
Select the point of interest to display the GRADE CONTROL - DEFINE RANGE OF HOLE IDS form.
String
Enter the string number to which each of the affected points will be assigned. The reason for defining a string number here is that in some circumstances a drill pattern may have been drilled with holes of different depths, azimuths, dips or sampling intervals. By differentiating holes with the same characteristics into different strings, the different characteristics can be easily assigned when loading the drill holes into the database.
Define the range of Hole ID numbers
Enter the Range to define the number of holes required and the values to be used for the hole IDs. This range is used to label and interpolate any number of new drill holes between the two selected endpoints. The range which you enter must define at least one value to interpolate new holes.
This function uses the hole formatting characteristics entered using the DEFINE HOLE ID FORMAT function.
Press Apply to interpolate and label the holes. After the holes have been interpolated and labelled you will be prompted to select the first point again. The function will continue until you press the Cancel button.
Any intervening points which need to be interpolated are created and labelled. Markers and labels are drawn on the screen to indicate the changes which have been made.
