This is done in Inventor. Making the diamond pattern basically involves doing the math to figure out exactly how big the diamond needs to be in each direction, depending on the number of diamonds you want and the desired thickness of the material between the holes. I don't know exactly what our student did in this one, but I've just made a couple of diamonds in a sketch, patterned them all the way out in two directions, then cut them all at once. Gray Adams' suggestion sounds good, because it would save you from having to cut the diamonds on the edges in half.
