*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, 
                                          p_strut_tube_lwr)

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.
