In building models, drawings can be pulled directly from the models allowing direct interaction. Schedules are also updated simultaneously. Modelled elements will also contain important data including; properties, who it was designed by, LOD, manufacturer etc. 
                  BIM allows for the management of  digital information throughout the whole life cycle of a structure, from  initial design all the way through to construction, maintaining and finally  de-commissioning. BIM is all about designing in 3D models rich with information  to allow for management of this data and collaboration between all the  disciplines.
