Follow the steps to achieve slide curve motion.

1. Step 1:

   Open the SlideCurve_without_kin.CATProduct document.

2. Step 2:

   Select the Slide Curve Joint icon .The Joint Creation: Slide Curve dialog box is displayed

3. Step 3:

   Click New Mechanism.The Mechanism Creation dialog box is displayed:
   In our example, keep the default name Mechanism.1.

4. Step 4:

   Select Curve 1 either in the geometry area or in the specification tree. In our example, select the yellow sphere arc as shown below:
   

   

5. Step 5:

   Select Curve 2 either in the geometry area or in the specification tree. In our example, select the line on the green part as shown below:
   

   

6. Step 6:

   Click Ok to end the slide curve joint creation.

7. Step 7:

   Now create a second joint (revolute joint) and a third joint (prismatic joint).

8. Step 8:

   Revolute.2:
   select line .1 (right white lines)
   select line.2 (left white lines)

   select xy plane ( green) (plane 1)
   select xy plane (white lines) (plane2)

   Select the Angle driven check box in the Joint Creation Dialog Box

   when done click OK
   

   

9. Step 9:

   Prismatic.3
   select line.1
   select line.2 as shown below:

   select xy plane (white lines) (plane 1)
   select xy plane (yellow sphere) (plane2)

   when done click OK
   

   

10. Step 10:

    This is what you will obtain.
    

    

11. Step 11:

    Click the Fixed Part icon in the Simulation toolbar or select Insert->Fixed Part... from the menu bar.

    Click the bottom cuboid for fixed part. (part 4)

12. Step 12:

    The mechanism can be simulated.

    Double-click Mechanism.1 in the specification tree.

    The Kinematics Simulation - Mechanism 1 dialog box is automatically displayed.
