Dear Wanshu,
A straight forward way to define these kind of structures is to create a function that returns your custom polygon (list of points) and create a Polygon mask element from the list of points:
from math import tan, radians
import nazca as nd
def triangle(length=10, angle=45):
base = 2*length*tan(radians(0.5*angle))
return [(0, 0.5*base), (0, -0.5*base), (length, 0)]
tri = nd.Polygon(points=triangle(length=50, angle=30))
tri.put(0)
tri.put(0, 10, 45)
nd.export_gds()Ronald
