AKL’s international terminal (on the left) was deceptively complex to draw. Though it was mostly straight lines, which are easier than curves, the majority of lines were not right angles or parallel. This effectively prevented me from rotating the drawing and using the rectangle tool, which added a lot of extra time.
Likewise, only one of the parts that appears curved is actually curved; the rest are a bunch of straight walls at slight angles to each other. This meant I couldn’t even use the ellipse or curve tools, and instead had to draw half a dozen or so guides each time just to get the angles consistent.
All in all, then, the international side took me quite a while to draw for what’s a relatively small terminal. At least the domestic terminal (right) was pretty quick to draw.
Since these terminal silhouettes are drawn to scale, I generally prefer compact airports to airports with widespread terminals, as the latter tend to add too much white space and distract from the intricacies of the terminals. So after drawing two Australian airports whose international terminals were on the other side of the airport from their domestic terminals, it was nice to be able to draw a single large structure for Melbourne.
This was also a relatively easy terminal to draw, as the vast majority of the walls were at right or 45° angles, and there weren’t many curves.
Likewise, while I was drawing ICT (Wichita), their old terminal was in the process of demolition. I’d initially indicated this by showing the old terminal as faded, but I’ve now gone ahead and completely removed it:
