34. On the SFD GG, how can I clear data and start a fresh SFD for a new city?

To clear all data and start a new SFD, click the reset button  located both at the top and bottom of the SFD Graphic Generator page. This will clear all input data - the city general information input boxes, the SFD Selection Grid and the SFD Matrix data - enabling you to start again. But before you do these, remember to save any data you want to keep.
