MIA was enjoyable to draw, even if it took a while. All of the angles on the interior of the terminal loop are 150°, which means that the concourse piers are generally a nice even 30° off of each other—for example, the angles between Concourses F and G or G and H are 30°. (The eastern part of Concourse E is itself rotated 10° off of perpendicular, but the western satellite of Concourse E is aligned to the 30° pattern.)
No two concourses used the same design—I’m assuming they were all built at different times with no real regard for maintaining a common layout.
