This is a tutorial for the model tutorial competiton and its about the design of tyre and rim in the AutoCad 2004

1. Step 1:

   Start AutoCAD and draw this profile. This will be tyre.
   

   

2. Step 2:

   Now draw the profile of the rim. Be sure to use polyline. If you used arcs and lines then use PEDIT command to join them.
   

   

3. Step 3:

   Draw a Construction line along X-axis.
   

   

4. Step 4:

   Use Revolve command and select the profile for rim.
   

   

5. Step 5:

   Revolve it about x-axis at 360º.
   

   

6. Step 6:

   Now we have the Rim body.
   

   

7. Step 7:

   Again revolve command and select the tyre profile.
   

   

8. Step 8:

   Revolve it by 8º.
   

   

9. Step 9:

   Now enter Rotate3D command.
   

   

10. Step 10:

    Select the tyre part.
    

    

11. Step 11:

    Along X-axis at -4º.
    

    

12. Step 12:

    Now draw these entities along the plane view using pline, pedit, rectangle. Any command.
    

    

13. Step 13:

    Enter Revolve command.
    

    

14. Step 14:

    Select the 2-entities.
    

    

15. Step 15:

    About X-axis at 4º.
    

    

16. Step 16:

    Now enter Subtract command.
    

    

17. Step 17:

    subtract the revolved part from tyre body.
    

    

18. Step 18:

    Revolve again and select the other two plines.
    

    

19. Step 19:

    About X-axis at -4º.
    

    

20. Step 20:

    Subtract them too.
    

    

21. Step 21:

    Enter 3DArray command.
    

    

22. Step 22:

    Select the tyre part.
    

    

23. Step 23:

    Polar array type.
    

    

24. Step 24:

    Enter number of items be 45. This will complete the tyre since it was rotated at 8º, 8x45=360º.
    

    

25. Step 25:

    Now we have the Tyre body.
    

    

26. Step 26:

    Plan>>Current View.
    

    

27. Step 27:

    Now we revolve two rectangle about x-axis at 360º.
    

    

28. Step 28:

    Subtract them too.
    

    

29. Step 29:

    Rotate the UCS.
    

    

30. Step 30:

    Plan>>Current view. Now use Cylinder command.
    

    

31. Step 31:

    Construct the cylinder.
    

    

32. Step 32:

    Move it to be symmetrical.
    

    

33. Step 33:

    Use Array command.
    

    

34. Step 34:

    Polar array with 4 items.Subtract them from the rim.
    

    

35. Step 35:

    Now we have the basic body of tyre in AutoCAD 2004 Standard Version.
