*InlineJoint() - inline joints (coincident origins)

Creates an inline joint with coincident i and j markers.

Syntax

*InlineJoint(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.; Data type: varname
joint_label: The descriptive label of the inline joint.; Data type: label
body_1: The first body constrained by the inline joint.; Data type: Body
body_2: The second body constrained by the inline joint.; Data type: Body
origin: The location of the i and j markers of the inline joint.; Data type: Point
AXIS: A required argument to indicate that the next token defines the axis along which the translational degree of freedom is allowed.
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.; Data type: Point or Vector

Properties

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

Comments

origin_1 is the location of both i and j markers, and point_1 or vector_1 defines the axis along which a translational degree of freedom is 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.
