Builtin Compos

You've already seen RectLW in The Basics of RAIMAD, a compo that represents a rectangle defined by length and width. RAIMAD offers four more built-in compos for you to use in your designs:

import raimad as rai

from math import radians

RectLW = rai.RectLW(100, 50)

circle = rai.Circle(radius=40)

ansec = rai.AnSec(
    theta1=radians(45),
    theta2=radians(180),
    r1=50,
    r2=80,
    )

rectwire = rai.RectWire(
    (0, 0),              # start point
    (80, 80),            # end point
    10                   # width
    )

triangle = rai.CustomPoly([
    (0, 0),
    (80, 0),
    (40, 80)
    ])

rai.show(RectLW)
rai.show(circle)
rai.show(ansec)
rai.show(rectwire)
rai.show(triangle)

AnSec

AnSec is short for "Annular Sector" which is how mathematicians say "pizza crust". There are many different ways to define an AnSec:

# Explicitly define inner radius, outter radius,
# angle one, and angle two

ansec = rai.AnSec.from_auto(
    theta1=radians(45),
    theta2=radians(180),
    r1=50,
    r2=80,
    )
rai.show(ansec)

# Make it go the other way

ansec = rai.AnSec.from_auto(
    theta1=radians(45),
    theta2=radians(180),
    r1=50,
    r2=80,
    )
rai.show(ansec)

# Instead of giving an explicit outter radius and second angle,
# define radius delta and angle delta

for x in (10, 40, 60):
    ansec = rai.AnSec.from_auto(
        theta1=radians(0),
        dtheta=radians(x * 3),
        r1=50,
        dr=x,
        )
    rai.show(ansec)

For all the options that AnSec takes, go read it's source code.

We will soon have documentation pages for all RAIMAD classes and functions. But for now, if you want to learn more about a class or function, you should go read its docstring.
