Colour Coding
Select this option if you want to colour code each blasthole collar based on the values in a colour field.
Select the field in the input file that contains values which will determine the colour to be used to depict the blasthole collars. The colour set, that is associated with this field, maps colours to text strings or numeric ranges. For each record in the file, the display colour is determined by the value in this field.

The position of new blasthole collars should not coincide with the position of the toes of the holes in the blasting block above. It is therefore sometimes necessary to be able to see the toes of the holes in the block that lie above the current block.
When you select the Display Only Bottom check box, the blastholes in the Input file are loaded as an Edit Locked layer and only the toes of the holes are visible. In addition to setting the display colour and the radius of the toes, an offset can also be set to allow for overdrilling, using either a specified offset value or the values in a nominated field.

Select this check box to display each blasthole trace in a nominated colour, line type and thickness.
