*VectorPair()

Creates a vector pair.

Syntax

*VectorPair(vector_name, "vector_label")

Arguments

vector_name: The variable name of the vector pair.; Data type: varname
vector_label: The descriptive label of the vector pair.; Data type: label

Example

*VectorPair(v_f_sp, "Front Spindle")

 p_f_wc.l.z-p_f_spal.l.z)
*SetVector(v_f_sp.r, p_f_spal.r.x-p_f_wc.r.x, 
 p_f_spal.r.y-p_f_wc.r.y, 
 p_f_spal.r.z-p_f_wc.r.z)
*SetVector(v_r_sp.l, p_r_wc.l.x-p_r_spal.l.x, 
 p_r_wc.l.y-p_r_spal.l.y,

Properties

Table 1.
Property	Returns Data Type	Description
l	Beam	Left vector.
label	string	The descriptive label of the vector pair.
r	Beam	Right vector.
state	boolean	Control state (TRUE or FALSE).
varname	string	The variable name of the vector pair.

Comments

The individual vectors of a *VectorPair() can be referred to as vector_name.l (left vector) and vector_name.r (right vector).
