Vector3D

The Vector3D class is a data holder for a 2D vector. The Vector3D is internally represented by a x and y value. The value unit is mm.

There are the following groups of member functions with some examples of use:

• construct the vector

  import NemAll_Python_Geometry as AllplanGeo
  
  vector1 = AllplanGeo.Vector3D()
  vector2 = AllplanGeo.Vector3D(1000, 2000, 3000)
  vector3 = AllplanGeo.Vector3D(vector2)
  ...
  

• set and get the values

  vector1.X = 500
  vector1.Y = vector2.Y
  length    = vector1.GetLength()
  ...
  

• changing the vector by basic mathematical operations like +, -, * and /

  vector4 = vector2 + vector3
  vector2 -= vector3
  vector5 = vector3 / 2
  ...
  

• comparing vectors

  if vector2 == vector3:
     ...
  ...
  

• general vector utilities like cross product, normalize, …

  vector3 = vector1.CrossProduct(vector2)
  dot_res = vector1.DotProduct(vector2)
  
  vector3.Normalize(1000)
  vector3.Reverse()
  

The Vector3DList class is a special list for Vector3D objects and can be used like

vector_list = AllplanGeo.Vector3DList() vector_list.append(vector1) vector_list.append(vector2) vector_list.append(vector3)
