I think some confusion might be that the location of the drawing is so far away from 0,0,0. as I opened it in Moi and initially didn't see anything.
I had to look at it in Max first and find out that the location is 208679'6.5", 93074'4.75", 34' 8.5"

Got the terrain made, buildings imported, I'm now projecting the streets onto the terrain :D

My computer is crying from the load... And it's a 12 core...
