No, I am not able to get it. Its completely different. What I want is to create those squares box in 15×15 wafer dimension having lattice constant=575nm. The file attached here will hopefully help you in getting what is meant to say. In the above file I have created the square boxes by clicking on the PBG Crystal Structure but it really consumes time and every time I need to do the same so I wondered to use some iteration kind of technique where I can specify the points and the boxes automatically fits to their desired place. Just let me know if you can get me or not.
