1. A computer implemented method for generating an operational user interface for a building management system, comprising: generating a widget using geometrical information associated with a building information modeling object and relationship information associated with the building information modeling object, wherein generating the widget includes: retrieving an air distribution loop system from the relationship information associated with the building information modeling object; obtaining three-dimensional geometrical information associated with the building information modeling object; rendering the air distribution loop system and the three-dimensional geometrical information as graphics of the widget; and forming the graphics into a whole graphic of the widget; assigning a state variable to the widget by analyzing properties of the building information modeling object and an ontology definition of the building information modeling object, wherein the ontology definition of the building information modeling object includes a naming convention of a class associated with the building information modeling object; associating the state variable with a point from the building operation system by mapping the point to the state variable; and changing the state variable based on input received from a user.
