Creates a bushing pair.

Syntax

*BushPair(bush_name,"bush_label",body_1, body_2, origin)

Arguments

bush_name: The variable name of the bushing pair.; Data type: varname
bush_label: The descriptive label of the bushing pair.; Data type: label
body_1: The first body or body pair constrained by the bushing pair.; Data type: Body or BodyPair
body_2: The second body or body pair constrained by the bushing pair.; Data type: Body or BodyPair
origin: The location(s) of the bushing pair.; Data type: Point or PointPair

Example

Table 1.
Property	Returns Data Type	Description
b1	BodyPair	The first body pair constrained by the bushing pair.
b2	BodyPair	The second body pair constrained by the bushing pair.
i	MarkerPair	The marker pair on b1.
j	MarkerPair	The marker pair on b2.
jfloat	MarkerPair	The floating marker pair on b2.
l	Bush	Left bushing.
label	string	The descriptive label of the bushing pair.
r	Bush	Right bushing.

Comments

The individual bushings of a *BushPair() can be referred to as bush_name.l (left bushing) and bush_name.r (right bushing).

The floating marker property, jfloat, is used only for nonlinear bushings.
