This routine takes two adjacent pits or blocks and
merges them to create just one. Routines such as Pit Matrix Layout
can sometimes leave small irregular shaped pits along complex
boundaries. Usually, the user would like to combine or add a small
sliver of a pit with an adjacent one so that the volume is
reported, but not as its own tiny pit. The volumes are combined if
they are stored in the pits as values.
There are two methods for selecting the pits to
merge. The Pick method prompts to pick points inside the pits to
merge. The Size method prompts for a minimum area size and then a
selection of pit polylines to process. Then any pits less than the
minimum area are merged with a neighboring pit. For the pick
method, pick first in the pit you want to keep, then in the pit you
want to remove. A new polyline is drawn around both, representing
the new pit with the same name as the first pit you picked inside
of. The last step is to simply erase the text of the smaller,
deleted pit (if they were labeled). If a pit is selected on or near
a line, then the pit is highlighted and you are prompted to hit
Enter to accept the pit or press N to highlight the other nearby
pit.
