There are two ways to create a Revolute Joint as shown in the figure below. Connecting properties such as the base and action bodies, and the location and rotational direction of the bodies are defined in the Revolute Joint creation dialog. When creating the joint, two markers are simultaneously created to represent the joint. When the Body-Body-Point option is used, the orientations of the two markers are created as the identity matrices. When Body-Body-Point-Direction option is used, the z-axes of the markers are defined as the rotational direction. The other axes of the markers are determined by the right hand rule. Parameters in the dialog are defined as shown in the table below.
Figure 5.22: Description of parameters in the Revolute Joint creation dialog
| Parameter | Description |
| 1. Base Body | Use to set the base body using the General Picker. This becomes a parent body of the base marker. |
| 2. Action Body | Use to set the action body using the General Picker. This becomes a parent body of the action marker. |
| 3. Position | Use to set the location of joint using the Point Picker. This defines the position of the base and action markers. |
| 4. Z-axis | Use to set the rotational direction using the Direction Picker. This defines the z-axis of the base and action markers. |
| 5. Name | Use to set the name of the revolute joint. |
| 6. Show Property Dialog | Use to open the property dialog after finishing the creation operation. |
| 7. Control buttons | If all necessary parameters are set, these buttons are enabled. For more information about the control buttons, refer to Entity Creation. |
