We use the hands of clocks to rotate to illustrate:
1. Draw the outline of the clock on the Drawing toolbar, select the Oval button, press SHIFT to drag the mouse to draw a circle, and format it with no fill color or line color.
2, the clock's pointer select the arrow button on the Drawing toolbar to draw an arrow. And then edit the vertex to adjust to the appropriate position.
3, the animation method of the pointer and the 2nd step of the "flashing" effect.
4, set the number of pointers to generate 60 arrows, the vertex to edit, adjust to the appropriate location, basic format such as figure. Set other animations at the same time, in the same way as the 2nd step of flashing.
