Display motion in Rack and Pinion through Drive Constraint.

1. Create a ‘New Assembly’ and save it with the name ‘Rack and Pinion - Drive Constraint’.
2. Select Place component from the marking menu and place the Pinion in the Assembly.
3. Align the Pinion in correct position by using View Cube.
4. Select the Pinion in the design window, right click and uncheck its Grounded status in the Assembly.
5. Open the visibility of Z Axis of Assembly and Z Axis of Pinion from the Browser Bar.
6. Apply a Mate Constraint between Z Axis of Assembly and Z Axis of Pinion.
7. Place a Mate Constraint between Centre Point of Assembly and Centre Point of Pinion.
8. Place the Rack in the Assembly and align it properly with Pinion by using Rotate Component Tool.
9. Apply a Tangent Mate between Pitch Circle of Pinion and Pitch Line of Rack.
10. Activate Angle Constraint, First select XZ Plane of Assembly, Second select XZ Plane of Rack and in the last Third select front face of Rack, click apply.
11. Open the visibility of YZ Plane of Pinion and Work Plane 7 of Rack; later apply a mate constraint between them.
12. Turn off the visibility of Work Plane to make the screen clear.
13. Set the browser from Assembly View to Modeling View using the toggle at the top of the browser.
14. Right click the Mate:3 in the browser and select Supress from the context menu.
15. Open the visibility of YZ Plane of Pinion and YZ Plane of Assembly.
16. Activate the Angle Constraint, First select YZ Plane of Assembly, Second select YZ Plane of Pinion and in the last Third select front face of Rack, click apply.
17. Turn off the visibility of Work Plane to make the screen clear.
18. Activate the Motion constraint, in the Type area select Rotation-Translation, and afterwards select the Pitch Circle of Pinion then Pitch Line of Rack. Fill the 4.725 inch in the Distance Input box and click OK.
19. Select the Angle:2 Constraint in the Browser and change its name as ‘Drive’ by clicking twice slowly.
20. Right click the Drive Constraint and select Drive Constraint Tool from the context menu.
