I am trying to figure out how to set up my cad files so the walls will import into Ekahau Site Survey program. Everything I have tried so far has had very sketchy results. Some walls come in, some don't, seemingly random. I have tried using AutoCAD LT and plines, AutoCAD Architecture and walls, even tried Visio. I can not find a way to consistently import the CAD file into Ekahau. Ekahau claims their software supports this type of import but they do not offer any advice on how to set the cad files up. Any information anybody has on this subject would be greatly appreciated.
