Co-ordinate Transformations

The latest part in My computer-aided engineering course in Fás. 2 Rectangular cycles (G76) make up the basic shape. Mirror (G28) is used to do the ones on the top left corner. Rotate (G73) for the one at an angle on the top right and scale (G72) for the larger shape. 3 of the small holes were drilled normally and then that section (or label) was rotated to save lines in the program for drilling the final 3 holes.
