AutoCAD example tutorial: the whole process of bearing modeling

I started to paint a bearing for the old farmer, which shocked me for a long time! I drew one in the morning, but the tray (bead hoop) is not an arc! I observed it carefully in the afternoon and built the model.

You can use a series of commands in combination, and hope to help newcomers.

First look at the final result:

Effect 1

Effect 2

Start the tutorial steps below:

First, create a polygon (my is 24 sides)

figure 1
Second, draw a circle with the center of one side as the center, as shown in the figure:

figure 2

Third, copy the circle, the center of the circle is placed at the midpoint of the edge, as shown in the figure:

image 3

Fourth, the overall copy, spare. as the picture shows:

Figure 4

Fifth, establish a yellow area.

Figure 5
Sixth, rotating yellow area

Image 6

7. Copy the finished product to the spare polygon.

Figure 7

Eight, mirror red line, connect

Figure 8

Nine, establish a domain

Figure 9

Ten, switch views, stretch, move

Figure 10

Eleven, draw two spheres

Figure 11
Twelve, ask for two difference sets

Figure 12

Thirteen, switch the view, transfer the finished product to the standby

Figure 13

Fourteen, draw the ball, and draw as shown in the auxiliary line

Figure 14

Fifteen, with the auxiliary line as the midpoint, array

Figure 15

16. Create a map area and mirror one

Figure 16

Seventeen, rotated 90 degrees

Figure 17
Eighteen, with the base point copy, as shown:

Figure 18

Nineteen, rotated 90 degrees, as shown:

Figure 19

Twenty, with base point copy, as shown:

Figure 20

Twenty-one, rotating two areas, as shown in the figure:

Figure 21

Twenty-two, the extra lines are classified as the same invisible layer, coloring, OK!

Figure 22

Twenty-three, plus a certain material.
