The whole process of the AutoCAD bearing modeling

Started the old farmer to draw a bearing, at that time shocked me for a long time! I drew one in the morning, but that tray (round bead hoop), not circular! After a careful observation in the afternoon, the model was built up.

Can be used to synthesize a series of commands, hoping to help the novice.

First look at the final effect:

Effect 1

Effect 2

Start the tutorial steps below:

First, build the polygon (my 24 side)

Figure 1

Second, take the center of one side as the centre, draw two separate circles, as shown in the figure:

Figure 2

Third, copy the circle, the center is placed in the midpoint of the pro side, as shown in the figure:

Figure 3

Four, the whole copy, standby. As shown in the figure:
