Expand dependencies act on solids in adjacent flitches or benches. Solids in the lower elevation are dependent on the solids in the higher elevation. |
The Expand Distance works by taking the polygonal boundary of a solid, expanding it by the nominated distance, and checking for any unfinished activities on the elevation above that are within that area.
A positive expand distance forces a minimum running track between crests and toes.
A zero expand distance allows vertical walls*.
A negative expand distance allows under-cutting the bench above by that amount.
...
*A zero expand distance technically allows vertical walls, but a value of (-1) or (-5) tends to get a better result. It gives the engine a bit more freedom to mine blocks that have tiny overlaps.
