Description

Depth of topsoil to be stripped

Enter the depth of topsoil that should be stripped from cross-sections before areas are calculated.

Maximum tolerance for areas

Enter the maximum difference between cut and fill areas (as a percentage) to accept as having optimised a cross-section. In other words, if the difference between cut and fill areas expressed as a percentage of the areas is less than or equal to the value entered here, the cross-section will be accepted as optimised.

Apply - Template or Batters

Select whether to apply a template or only recalculate batters when optimising.

If Batters is chosen, there must be at least three points present in the batter layer so that the batters can be applied to something. A preliminary pass through the Vertical alignment and Edge Levels is the recommended way of getting these three points.

If Template is chosen, the specified template will be used to build an entire road profile just like the template testing facility in the Template Editor. No preliminary information is required.
