The transform is 45 degree counter-clockwise rotation, scale factor = 1, shift of (20,20,0) meters. The point SP001 is at the origin, (0,0,0) in the original *.nez file. After transform, the point, SP001, is at (20,20,0). The grid rotates counter-clockwise (or the survey points appear rotated clockwise).

Figure 64 shows the modified survey file after plotting with Qcad. The new *.nez file is samp000.mod.
