Program will recompute the grid locations and show those as X1, X2, X3… and Z1, Z2, Z3…etc. and show in the two lists. The grid based patterns must have symmetric grid placed with respect to the origin (mid) of the pattern.
You can adjust the location of grid lines at X and Z intervals. If you would like to revise, simply select the entry and modify it. Note that X1 is the distance of a grid location which is farthest from the pattern origin. X2 is the second farthest and so on. Similarly Z1 is the distance of the grid farthest in Z direction. Z2 is the second farthest and so on. These distances are shown in the plot and each grid intersection is a check box and a place where a pile can be placed. If you do not want to place a pile at a location, make sure the corresponding box is unchecked. To set/remove piles at all locations click Select/Unselect all. Click OK once all the pile locations are specified. Click cancel if you do not want to make any changes to the placement positions.
