在ipkiss中，通过Polygon可以直接获取任意shape的面积：

from si_fab import all as pdk
import ipkiss3.all as i3
from shapely.geometry import Polygon

class Shape(i3.PCell):
    class Layout(i3.LayoutView):
        def _generate_elements(self, elems):
            elems += i3.Boundary(
                layer=i3.TECH.PPLAYER.SI,
                shape=[(0, 0), (7.7, -23.7),
                       (32.6, -23.7), (12.4, -38.4),
                       (20.1, -62.1), (0, -47.4),
                       (-20.1, -62.1), (-12.4, -38.4),
                       (-32.6, -23.7), (-7.7, -23.7)])
            return elems

if __name__ == '__main__':
    Shape().Layout().visualize()
    shape = Shape().Layout().elements[0].shape
    area = Polygon(shape).area
    print("The area is: {}".format(area))

通过Polygon：

area = Polygon(shape).area

就可以直接获取面积。
