*CVJoint()
Creates a constant velocity joint.
Syntax
*CVJoint(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.
- joint_label
- The descriptive label of the constant velocity joint.
- body_1
- The first body constrained by the constant velocity joint.
- body_2
- The second body constrained by the constant velocity joint.
- origin
- The location of the constant velocity joint for body_1.
- POINT|VECTOR
- A keyword that indicates the alignment method.
- point_1|vector_1
- An entity variable referring to a Point or Vector 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 or Vector which is based on the above keyword.
- ALLOW_COMPLIANCE
- An optional argument that indicates the joint 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 ALLOW_COMPLIANCE argument is optional. When it is included, it indicates that the joint can be made compliant. In compliant mode, such a joint acts as a bushing.
The isbush property is valid only for joints that can be made compliant. When isbush is set to FALSE, the joint acts like a kinematic joint (in a noncompliant mode). When isbush is set to TRUE, the joint acts like a bushing (in a compliant mode). When the compliant option in a system is switched to "non-compliant", all the joints in the system act as kinematic joints. However, when the system option is switched to "compliant", only the joints that are created with an ALLOW_COMPLIANCE flag act as bushings. The rest of the joints continue to behave as kinematic joints.
