B.3.5 3-D Matrix Grid
A three-dimensional (3D) grid file sequence begins with the ID number that refers to
the first column, the first row, and the first point. Then the point (or column, or row)
increments one value at a time until the sequence reaches the last point (or column, or
row) value while the other two dimension values stay constant. Then, another
dimension increments from its first to its next value. This continues until the ID
number that refers to the last column, last row and last point is reached. You can select
either columns, rows, or points to increment first and one of the remaining two
selections to increment second.
How is a 3-D grid used? A 3-D grid structure may associate two dimensions of the
grid (for example, the columns and rows) with the physical coordinates on the part
whose wall thickness is to be measured. The particular measurement points on each
part are then associated with the third dimension of the grid. This scenario enables
multiple readings to be stored at each grid coordinate (see Table 30 on page 318).

Start Col = A
End Col = F
Start Row = 1
End Row = 4
Start Point = X
End Point = Z
