*CVJointPair()
Creates a constant velocity joint pair.
Syntax
*CVJointPair(joint_name,"joint_label",body_1, body_2, origin, POINT|VECTOR, point_1|vector_1, POINT|VECTOR, point_2|vector_2, [ALLOW_COMPLIANCE])
Arguments
- joint_name
- The variable name of the constant velocity joint pair.
- joint_label
- The descriptive label of the constant velocity joint pair.
- body_1
- The first body or body pair constrained by the constant velocity joint pair.
- body_2
- The second body or body pair constrained by the constant velocity joint pair.
- origin
- The location(s) of the constant velocity joint pair for body_1.
- POINT|VECTOR
- A keyword that indicates the alignment method.
- point_1|vector_1
- An entity variable referring to a Point, PointPair, Vector, or VectorPair which is based on the above keyword.
- POINT|VECTOR
- A keyword that indicates the alignment method.
- point_2|vector_2
- An entity variable referring to a Point, PointPair, Vector, or VectorPair which is based on the above keyword.
- ALLOW_COMPLIANCE
- An optional argument that indicates the joint pair can be made compliant.

Comments
When a point is used (instead of a vector) to define an axis, it is obtained as the direction from the origin of the joint to the specified point.
The individual joints of a *CVJointPair() can be referred to as joint_name.l (left constant velocity joint) and joint_name.r (right constant velocity joint). The ALLOW_COMPLIANCE argument is optional. When it is included, it indicates that the joint pair can be made compliant. In compliant mode, such joint pairs act as bushing pairs.
The isbush property is valid only for joint pairs that can be made compliant. When isbush is set to FALSE, the joint pairs act like kinematic joints (in a noncompliant mode). When isbush is set to TRUE, the joint pair acts like a bushing pair (in a compliant mode). When the compliant option in a system is switched to "non-compliant", all the joint pairs in the system act as kinematic joints. However, when the system option is switched to "compliant", only the joint pairs that are created with an ALLOW_COMPLIANCE flag act as bushing pairs. The rest of the joint pairs continue to behave as kinematic joints.
