I threw together a
real quick massing model just to try to visualize what this would look like "square" from the harbor. From what I've seen, it looks like the second-from-highest roof (the top of the tube adjacent/east of the tallest tube) of 2 WTC is about the same height as the top 3 WTC, give or take. My rendering pushes that roof line a little lower because tower 2 is further from the camera than tower 3.
Please ignore my very inaccurate facade. I just threw it together really quick, and I tried my best to consider perspective and the footprint. It's my best attempt.
Does this look close? Or have I missed the mark?
(Also, I forgot where I found this photo from, but it might have been on Skyscraperpage, so credit is due to whomever posted this; my bad for not keeping track. If I crossed a line I can delete this post.)
