Fire escape modeled in 3DS Max 9. 15.680 polys and 15.872 verts
for 3-story fire escape with stairs and upper and lower ladder.
Polygonal geometry. Can fit any building. Logicaly split in
segments (upper platoon, lower platoon, stairs, upper ladder,
lower ladder) for easy manipulation. Contains two different
types (400cm and 250cm between platoons), but can be easly
adjusted to fit any distance between floors.
