 The most typical example of a joint would be in gait, the GRF is applied to the foot segment, and because there is a joint at the ankle, the force is applied from the foot segment to the shank segment.

 Essentially, a joint is created if the proximal and distal ends of two segments are close to each other.

+===== Default Joint Names =====
+Visual3D creates joint names automatically for the default segments.
+Visual3D contains a number of default segment names that are provided for the convenience of the user. These default segments contain geometry, the inertial properties, and the wire frame model. Users that create their own segment names need to add this information in the segment properties tab in Model Builder Mode
+The calculation of Joint Moment, Joint Power, and Joint Force refer to the proximal end of the segment selected. For convenience we have mapped segment names to joint names automatically because we assumed that users would find it more intuitive.

+if a default name doesn't exist for a segment you have created, Visual3D, for the purpose of creating model based items specifies the joint name as "segmentName_JOINT".
+===== How to visually check for joints =====
 If you have a model template applied to a static trial, you will be able to see if joints are created between segments. You can also view the joints in the example CMO file.

 If you do not see joints, make sure that you have the option to see joints on by right clicking in the 3D viewer and selecting View Joints.

 You can also change the size of the spheres by going to Settings -> Modify Scale of 3D Graphics Objects, and changing the Joint Size option.
