Point2D

The Point2D class is a data holder for a 2D point. The Point2D is internally represented by a x and y coordinate. The coordinate value unit is mm.

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

• construct the point

  import NemAll_Python_Geometry as AllplanGeo
  
  point1 = AllplanGeo.Point2D()
  point2 = AllplanGeo.Point2D(1000, 2000)
  point3 = AllplanGeo.Point2D(point2)
  ...
  

• set and get the coordinate values

  point1.X = 500
  point1.Y = point2.Y
  ...
  

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

  point4 = point2 + point3
  point2 -= point3
  point5 = point3 / 2
  ...
  

• comparing points

  if point2 == point3:
     ...
  ...
  

• general point utilities like get distance, …

  dist = point2.GetDistance(point3)
  ...
  

The Point2DList class is a special list for Point2D objects and can be used like

point_list = AllplanGeo.Point2DList()
point_list.append(point1)
point_list.append(point2)
point_list.append(point3)
