 Defining the segment coordinate system for the humerus is particularly difficult because there are no bony landmarks to assist in determining the glenohumeral joint center, and medial and lateral markers on the epicondyles are close together and often do not represent the axis of rotation of the elbow.

   * The radius value for the proximal end of the upper arm is half the diameter of the upper arm at the level of the head of the humerus. The radius value for the distal end of the upper arm is half the diameter of the upper arm at the level of the elbow.

 Joints are a "book keeping" object in Visual3D because 6 degree of freedom segments don't have an anatomical joint. **//Joints//** are created to express the location at which the interaction torques and moments are applied between segments.
