*InlineJointPair() - inline joints (coincident origins)

Creates an inline joint pair with coincident i and j markers.

Syntax

*InlineJointPair(joint_name,"joint_label",body_1, body_2, origin, AXIS, POINT|VECTOR, point_1|vector_1)

Arguments

joint_name: The variable name of the inline joint pair.; Data type: varname
joint_label: The descriptive label of the inline joint pair.; Data type: label
body_1: The first body or body pair constrained by the inline joint pair.; Data type: Body or BodyPair
body_2: The second body or body pair constrained by the inline joint pair.; Data type: Body or BodyPair
origin: The location of the i and j markers of the inline joint pair.; Data type: Point or PointPair
AXIS: A required argument to indicate that the next token defines the axes along which the translational degrees of freedom are allowed.
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.; Data type: Point, PointPair, Vector, or VectorPair

i	MarkerPair	The marker pair on b1.
j	MarkerPair	The marker pair on b2.
l	InlineJoint	The left inline joint.
label	string	The descriptive label of the inline joint pair.
r	InlineJoint	The right inline joint.
state	boolean	Control state (TRUE or FALSE).
varname	string	The variable name of the inline joint pair.

Comments

The individual joints of a *InlineJointPair() can be referred to as joint_name.l (left inline joint) and joint_name.r (right inline joint).

PointPair origin is the location(s) of both i and j marker pairs and, point_1 or vector_1 define the axes along which the translational degrees of freedom are allowed.

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.
