Drillhole Fence Diagram Tab - Reference Grid
Use this tab to specify the parameters for a reference grid displayed on the fence
diagram plot. The easting and northing axes plot as vertical lines, and the elevation (or relative level) axis plots as horizontal lines.

Reference Grid Properties

|
Plot grid?
|
Check to plot a reference grid on the map.
|
Horizontal axis
|
|
Options
|
Select a horizontal axis option, None, Along fence, Eastings, or Northings.
The Along fence option begins with zero at the left-most hole,
and measures the distance from hole to hole, increasing from left to right.
The Eastings and Northings options plot the intersection
points of the individual Easting and Northing values with the fence section trace.
|
|
Grid Interval
|
Specify the grid interval of the horizontal axis. If this is left blank a "nice"
value is determined automatically.
|
Elevations
|
|
Plot elevation grid lines
|
Check to plot elevation grid lines. See the important note below Elevations
in Fence Diagrams.
|
|
Grid interval
|
Specify the grid interval of Z-scale. If this is left blank a "nice" value is determined
automatically.
|
Attributes (mm)
|
|
Font
|
Use the drop-down list to select the Font to use to annotate the reference grids.
|
|
Label size
|
Specify the label size in map sheet units (millimetres).
|
|
Line thickness
|
Specify the line thickness in map sheet units (millimetre).
|
|
Cross size
|
Specify the cross size in map sheet units (millimeters). Crosses mark the intersections of the Easting and/or Northing grid axes with the horizontal elevation (Relative Level) grid axes. The cross size is the full length of each bar in the cross.
|
|
Border tick length
|
Specify the border tick length in map sheet units (millimeters).
|
|
Colour
|
Click inside the colour box and the Colour tool will be displayed.
|
|
Grid line type
|
Use the drop-down list to select the Grid line type.

Elevations in Fence Diagrams
In fence diagrams, the holes are plotted vertically, even if they are dipped or
curved. The hole collars are plotted at the "correct" elevations, but, unless the
holes are vertical, the elevations for any data below the hole will not be correct,
in fact the observed elevation will be higher in reality. For this reason, it is
recommended that elevations only be plotted for holes that are substantially vertical.
