Drill Hole Display
Display trace of blastholes
Select this option to display the blastholes as a hole trace. You will need to specify the colour and line type for the blasthole trace. The colour is selected from the current colour table, and the line type (and line thickness) from a list of line types delivered with Vulcan. The following options are available when displaying blasthole traces:
Display primitive of hole
Select this check box to display the hole trace as a circular primitive, thus showing the holes as cylinders giving them weight.
Note: You must have a primitives file (.pgd) in your current working directory to use primitive displays on drillholes. If you choose to display primitives in this panel and a primitive file does not already exist in your working directory, then Vulcan will create one automatically. If you copy an existing.pgd file into your working directory it must be named with the project (.dg1 file) prefix. That is, <proj>.pgd. For more information about Primitives, go to Design > Attribute Edit > Create/Edit Primitives.

Mark toe location with a cross
