Pit Polygons

Line colour, type, and width settings on the Pit Design | Pit Polygons tab are set by default when the form is cleared (or used the first time). These default colours have been tested for clarity against both a white and a black background.

You can select the Display settings from file option to use the settings from the input file, or select Custom display settings and configure the following:

Type	Description
Base	A Base string is the perimeter string for the base of the pit design.
Toe	A Toe string is the bottom string of a pit or stockpile.
Crest	A Crest string is generated as the pit or stockpile expanded. A crest (with the exception of the final crest) has a corresponding Toe string at the same Z or elevation.
Road	A Road string is generated when you add a Road. A Start point is defined on a Crest or Toe string.
Road Centre-line	You can choose to display a road centre-line (on the Input tab). The centre-line is the line along which the gradient and the length of the road are calculated.
Slot Ramp	A Slot Ramp string is generated when you add a Slot Ramp. A Slot Ramp is an alternative to a spiral road and is suited to shallow pits.
Drainage Toe	A Drainage Toe string denotes the location of water drainage at the base of a bench or a slope.
Guide Contour	A Guide Contour string between successive Toes and Crests can be used to denote benches.
