Edit the sketch to add a Point for the Pin-Joint of the Rocker.

STEP 1: Double-click the Part that is the slider to edit the sketch tool sketch.

STEP 2: Add a sketch to the original tool sketch.

In the sketch, we need a Point for the Pin-Joint, and a Line for the Motion-Dimension FB - as we will add a Rocker.

STEP 3: Close the Part-Editor

STEP 14: Edit the Motion-Dimension | Edit the BASE-Value to -130

STEP 15: Add a Motion FB and Linear-Motion FB.

STEP 16: Connect the Function-Blocks

STEP 17: Cycle (ALT+C) to preview the design.

You will notice the Slider moves back and forth by 100mm and the Rocker oscillate by 100º – at the same time.

Q: Why is the motion the same?

A: We have linked the same Motion in MotionDesigner to the two Motion-Dimension FBs.
