Vertex¶

Besides coordinates as a list such as [[x1, y1], [x2, y2]] anaStruct also has a utility node class called Vertex Objects from this class can used to model elements and allow simple arithmetic on coordinates. Modelling with Vertex objects can make it easier to model structures.

from anastruct import SystemElements, Vertex

point_1 = Vertex(0, 0)
point_2 = point_1 + [10, 0]
point_3 = point_2 + [-5, 5]

ss = SystemElements()
ss.add_element([point_1, point_2])
ss.add_element(point_3)
ss.add_element(point_1)

ss.show_structure()
