*OrientJoint()

Creates an orient joint.

Syntax

*OrientJoint(joint_name,"joint_label",body_1, body_2, origin_1, origin_2)

Arguments

joint_name: The variable name of the orient joint.; Data type: varname
joint_label: The descriptive label of the orient joint.; Data type: label
body_1: The first body constrained by the orient joint.; Data type: Body
body_2: The second body constrained by the orient joint.; Data type: Body
origin_1: The location of marker i attached to body_1.; Data type: Point
origin_2: The location of marker j attached to body_2.; Data type: Point

Example

Properties

Table 1.
Property	Returns Data Type	Description
b1	Body	The first body constrained by the orient joint.
b2	Body	The second body constrained by the orient joint.
i	Marker	The marker on b1.
id	long integer	Solver identification number.
j	Marker	The marker on b2.
l	Beam	Left beam.
label	string	The descriptive label of the orient joint.
state	boolean	Control state (TRUE or FALSE).
type	string	Unique joint type.
varname	string	The variable name of the orient joint.

Comments

An orient joint constrains all three relative rotations between the two bodies. The relative translations, however, are unconstrained.
