*InlineJointPair() - inline joints (non-coincident origins)

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

Syntax

*InlineJointPair(joint_name,"joint_label",body_1, body_2, origin_1, ORIGIN, POINT, origin_2)

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_1: The locations of the i marker of the inline joint pair.; Data type: Point or PointPair
ORIGIN: A required argument to indicate that the next token is the location(s) of the j markers.
POINT: A keyword that indicates the alignment method.
origin_2: An entity variable referring to a Point which is based on the above keyword which provides the location(s) of the j markers of the inline joint pair.; Data type: Point or PointPair

Example

*BodyPair(b_strut_rod, "Strut Rod",   p_strut_rod_cm)
*BodyPair(b_strut_tube, "Strut Tube", p_strut_tube_cm)
*PointPair(p_strut_rod_lwr, "Lower Strut Rod Point")
*PointPair(p_strut_tube_lwr, "Lower Strut Tube Point")
*InlineJointPair(j_strut_lwr_inlinejprim, "Lwr strut inline joint"
                                          b_strut_rod, 
                                          b_strut_tube, 
                                          p_strut_rod_lwr, 
                                          ORIGIN, 
                                          POINT,

Properties

Table 1.
Property	Returns Data Type	Description
b1	BodyPair	The first body pair constrained by the inline joint pair.
b2	BodyPair	The second body pair constrained by the inline joint pair.
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).

Origin_1 and origin_2 are locations of the i and j markers, respectively. The axes formed by connecting origin_1 and origin_2 is the axes along which translational degrees of freedom are allowed for the joint pair.
