In this step, we connect these Function-Blocks (FB):
•A Linear-Motion FB
•A Motion-Dimension FB
•A Motion FB and a Gearing FB
These FBs, together, specify how and when a Crank, Rocker or Slider moves.

A Rocker is a Part that rotates around a Pin-Joint with a motion as defined by motion-values at the input-connector of a Motion-Dimension FB. |
|
The image shows a Rocker. To add a Rocker: 1.Add a Motion-Dimension FB to a Pin-Joint 2.The Base-Value is 40º 3.Add a Motion FB 4.Add a Linear-Motion FB 5.Drag wires to connect the Linear-Motion FB to the Motion FB to the Motion-Dimension FB To edit the FBs, double-click the FB icons or see How to open an Element's dialog-box |

A Slider is a Part that reciprocates, back-and-forth, along a Slide-Joint. |
|
The image shows a Slider. To add a Slider: 1.Add a Motion-Dimension FB to a Slide-Joint The initial position, here 110mm 2.Add a Motion FB 3.Add a Linear-Motion FB 4.Connect the Linear-Motion FB to the Motion FB to the Motion-Dimension FB. |
