This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 this is a highly detailed model of the former 3 World Trade Center which was leased by Marriott. The structure was opened in 1981 and was destroyed when 2 World Trade Center (the south twin tower) collapsed on top of it on 9/11. A detailed model of the lobby will follow soon. Unfortunatly due to an error, the model cannot be updated. I'm trying to get a solution to this problem.
