Pin-Joint :

A joint that constrains two Parts to rotate relative to each other about a Point in each Part.

The technical kinematic terminology for a Pin-Joint is Revolute-Joint.

STEP 1: Start the Add Pin-Joint command

1.Expand the Kinematic-elements toolbar

2.Click Add Pin-Joint

In the image we can see the:

Add Pin-Joint command in the toolbar is active

Mouse-Pointer for Add Pin-Joint is active.

GST-1-4-2

STEP 2: Add the Pin-Joint

1.Click the Part's start-Point - at start-Point is at the intersection of the Part's XY-axes

2.Click the start-Point of the Line that is on the Y-axis of the Base-Part.

Note

If you attempt to click, but miss, the second start-Point, you must click the two elements again.

GST-1-4-3

Result

The start-Point of CAD-Line in the Part snaps to the start-Point of the Line that is in the Base-Part.

The Part can now rotate relative to the Base-Part

The Pin-Joint is the rotating axis.

The symbol of the Pin-Joint element, when it is with a Point in the Base-Part, is this

STEP 3: Clear the Add Pin-Joint command

•Click Kinematic-element toolbar > Add Pin-Joint to the left of the graphics-area

•Press the ESC key on your keyboard

•Do a different command

Save your mechanism with CTRL+S
