Merge Pits

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.
