Option to send shallow dirt down to the next bench for drilling and mining.

Bench area above (blue) and below (brown) the thickness threshold value.

Draw a polygon around the shallow dirt to send down to the next bench.

To update bench preconditioning:

Scroll through the level tree to find the latest dig faces.
- Benches with existing polygons are formatted bold green.
- Benches with high estimated contour have a high value in the EstCon column.
Draw (or extend) polygons to encompass shallow floors or batter trims.
For each polygon, choose to Send Down, Remove the interior area, or if an area is to be mined with the bench above, choose to Send Up.
The default setting is Send Down, to update click on the polygon and go to properties window beneath the graphics window and click the drop down arrow.
The Remove column allows entire benches to be removed by checking here.

The estimated contour (EstCon) value for each bench is calculated using the Contour Height field in Setup > Phase Details.
