BIM ?BIM ?

Models that contain 3D data only and no object attributesModels that contain 3D data only and no object attributes.

Models with no support of behavior[i e models that do not utilize parametric intelligence][i.e. models that do not utilize parametric intelligence]

Models that are composed of multiple 2D CAD reference files that must be combined to define the buildingmust be combined to define the building

Models that allow changes in one view that are not automatically reflected in other viewsreflected in other views
