How to draw a triangle

[Wanshu]

Dear Nazca team,

 

I would like to draw a triangle with knowing a length and two angles.

Within the geometries module, I saw rectangle, tetragon and trapezoid, but no triangle.

BR,

Wanshu

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()
