I am trying to build a network including the sidewalks and streets for a campus and to be able to route someone from one building to another or from a certain room in a building to another room across campus. I was wondering if there is a way to do this when the network analyst always asks for addresses, since I do not have the address for every building on campus. Also, in my network I have different wheelchair impediments like stairs, so my network has to be able to be used for people in wheelchairs as well. All of my buildings on my map have imported from cad files and georeferenced to my background image. If anyone has an idea of how to create this network let me know! Thanks!
