ex1 ---- draw a plane with dip direction = 20 and E of N and dipping 30 degrees draw the pole to the plane mentioned above， draw a small circle centered at an azimuth of 280 degrees, plunging 40 degrees and 20 degrees in diameter 画了断层面为倾向以及倾角，接着画了极轴，又画了一个滑动方位角为280，滑动角为40 半径为20
ex2 ---- draw a plane with dip direction = 135 and E of N and dipping 61 degrees rake=0
ex3 ---- draw a plane with dip direction = 190 and E of N and dipping 45 degrees rake=260
ex4 ---- draw a plane with dip direction = 135 and E of N and dipping 61 degrees rake=180
ex5 ---- draw a plane with dip direction = 135 and E of N and dipping 61 degrees rake=90
0 degrees represents a left handed strike slip fault.
90 is a pure thrust,
180 a right handed strike slip,
270 a pure normal fault.
