So even just looking at the name of the station you know this is another hard one... it spans 4 blocks right off the bat! Although, the reason this is a tricky one has more to do with the fact that it's a combination of a large complex that is the Rockefeller Center and the subway station itself. It's hard to draw the line between which is part of the station and which isn't, since there are a few spots underground where the station mezzanine connects directly to the buildings above ground, and some of them connect to concourses. I'll take more pictures next time!
Work in Progress -
I tried to model the entire area of Manhattan below Central Park in 3D but turns out the lines are too thin and the changes in elevations look to subtle when you zoom out in a bird's-eye view. So I had to exaggerate the width of the tracks. But after rebuilding the 2D lines in Rhino the lines look so wiggly, so it looks a little weird now. I will try to make a cleaner and neater version!
