   I will use the body created in previous tutorial on Creating helical gear in AutoCAD.
   

   

2. Step 2:

   Enter MIRROR3D command.
   

   

3. Step 3:

   Select the gear body to mirror and press enter. Now it asks for 3 points of the mirror plane.
   

   

4. Step 4:

   We will select the three vertex of the gear body of the top plane. First one is like this.
   

   

5. Step 5:

   Now we have the body mirrored.
   

   

6. Step 6:

   Enter union command.
   

   

7. Step 7:

   Select both bodies and press enter. Now we have herring bone gear created in AutoCAD.
   

   

8. Step 8:

   Subtract a cylinder from the gear body and we have the required gear.
