Hi everyone! I'm trying to construct a 3D network for building interiors (I'm absolutely new on 3D!!!), and maybe my question is so obvious, but: do I need to draw on a separate feature class elevators and stairs??? In the example here: http://www.arcgis.com/home/item.html?id=d6bd91b2fddc483b8ccbc66942db84cb every floor is on a separate feature as floor transitions (elevators and stairs) and I would like to know if it is the only way to obtain routes inside buildings. Thank you in advance!!!!!!! lidia
