Vector
Class Vector()
Vector(parent='MODEL', name='Vector_n', label='Vector_n',
active=True, x=1, y=0, z=0)
3D Vector.
angle, normalize
Keyword Arguments
Argument  Data Type  Description  Default 

name  String  The variable name.  Vector_n, for next available integer n. 
label  String  The descriptive label.  Vector_n, for next available integer n. 
parent  Object  The parent.  MODEL 
active  Bool  Used to activate or deactivate this entity.  True 
x  Double  The x component.  1 
y  Double  The y component.  0 
z  Double  The z component.  0 
Notes
1. The parent parameter can only be initialized by the constructor and should not be modified directly.
2. Only parent can be used as a positional argument in the constructor.
Methods
 angle(other, degrees=False)

Calculates angle between two vectors.
other str Name of the second vector. Can also be a python object. degrees Bool If True returns the angle in degrees. False Returns:
Angle between self and other.
Return type:
Double
 normalize()

Normalize the vector.
Returns:
Normalized vector.
Return type:
Vector
Vector Pair
Class VectorPair()
VectorPair(parent='MODEL', name='VectorPair_n', label='VectorPair_n', active=True, sym='NONE')
3D vector pair.
Keyword Arguments
Argument  Data Type  Description  Default 

name  String  The variable name.  VectorPair_n, for next available integer n. 
label  String  The descriptive label.  VectorPair_n, for next available integer n. 
parent  Object  The parent.  MODEL 
active  Bool  Defines if entity is activated when True or deactivated when False.  True 
sym  Enum  The symmetry of pair entity. Takes values 'LEFT' for left entity as leader, 'RIGHT' for right entity as leader or 'NONE' when it is not symmetric.  ‘NONE' 
Instances
Instance  Type  Description 

l  Point  The left point. 
r  Point  The right point. 
Notes
Instance is a reference to an entity. You cannot modify an instance, but can modify its properties.
Examples
========
Create a vector, modify its properties and perform different operations on the vector
>>> #Create a Vector and set its x, y and z component
>>> v1 = Vector(name='v_1', label='Vector_1', x=1, y=2, z=3)
>>> v2 = Vector(name='v_2', label='Vector_2', x=3, y=0, z=1)
>>> #Unary minus
>>> v3 = v1
>>> v3.x

>>> v3.y

>>> v3.z

>>> #Addition
>>> v4 = v1 + v2
>>> v4.x

>>> #Subtraction
>>> v5 = v1  v2
>>> v5.x
