Here is how Rack and Pinion Mechanism can be created in CATIA

1. Step 1:

   Open Create_Rack2.CATProduct document.

2. Step 2:

   Click the Rack Joint icon in the Kinematics Joints toolbar or select Insert -> New Joint ->Rack... from the Menu bar.

3. Step 3:

   Select Prismatic.2 in the specification tree.

4. Step 4:

   Select Revolute.1 in the specification tree.
   

   

5. Step 5:

   Assign a command, for instance select Angle driven for revolute check box.
   

   

6. Step 6:

   Click Ok to end the rack joint creation.The rack joint is created and identified in the specification tree.
   Your mechanism can be simulated, a message is displayed.

7. Step 7:

   Double-click Mechanism.1 to launch the simulation with commands functionality.

8. Step 8:

   let's modify the ratio.
   Double-click Rack.3 in the specification tree
   

   

9. Step 9:

   Click the Define button.
   The Rack Ratio Definition dialog box appears:
   

   

10. Step 10:

    Select a circle in the geometry area. The ratio is automatically calculated.

    

11. Step 11:

    The ratio is automatically calculated.
    

    

12. Step 12:

    Click ok. Your Mechanism can be simulated.
