PS. Expand
- iarmstrong
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.
Populate multiple values in the Expand Distance column in meters or press black cross button to clear related.
