I have tried repetitively to get these models to import into the model with no success. I placed the building at the location I want it in Civil 3D and then try to import them into the data base with no success. I have attempted using the dwg import as well as converting to a dwf and importing as a 3D model both yielded no results. According to the wiki help I am doing everything that it says for procedure. But once I try to configure the model I either get an error or an incomplete model. I will attach the two files I am talking about.
