This command automates the connecting of dots for pillars and perimeters.
AutoMine Connections draws the pillars and perimeter of a mine based on point data in an offset file. This file can be created by one of the Mine Note Entry commands. There are two types of points in this file, corner points and regular points. Corner points, which appear as green dots, identify the first point across a cross cut for both the left and right side of a spad. Regular points are all other points, and are drawn as red circles. Corner points are critical to AutoMine. If a corner point is missing, AutoMine will become offset and the pillars will appear shifted. Each pillar must have exactly two corner points, one on the left and the other on the right. There can be no regular points between the two corner points on the pillar since AutoMine always directly connects the corner points together. For the perimeter, corner points are not important for the left and right faces. At the end face, however, corner points are required in order to identify the cross cut between the perimeter and the farthest pillar.
The order of entry of points in the offset file is significant in several ways. For one, the spads need to be in left to right order in the direction of mining. To do this, the spads can be entered in order, or the spads can be assigned sequential entry numbers. Another reason to assign entry numbers to the spads is to allow appending of the offset file. When reading appended files, AutoMine will group spads according to their entry number. The spads with the same entry number may be entered in any order since AutoMine sorts these spads by the distance along the direction of mining. For example, provided that spad 2 and spad 4 have the same entry number, then spad 2 and spad 4 offsets may be entered either spad 2's offsets then 4's or spad 4's offsets then 2's. The offsets within each spad, however, are not sorted, but are drawn in order. Consider, for instance, the cut in the left face of the perimeter in the figure below. These points must be entered in the order 1 then 2 then 3 then 4.
AutoMine removes any pillar or perimeter that is already in the drawing at the same location.
After drawing the pillars and perimeter, AutoMine leaves a pick
box hanging off the perimeter so that you may connect it with a
previous perimeter.
