1.0 BIM Objects

This section of the standard describes what an object is.

   1.1 BIM components and assemblies
This sub-section of the standard discusses the concept of individual BIM objects and BIM object assemblies. Defining the broad requirements for each.
 1.1.1  Bim Objects
   BIM objects shall be modelled as a component object or a system object.
 
  • Component objects are discrete, or loadable, objects where the geometry is created by the object modeller and represents a specific physical element or component.
  • System objects are objects where the geometry is provided by the BIM authoring system for the user to configure. Typically, these are layered objects such as walls, floors, roofs and ceilings, but can also include, in some BIM authoring systems, windows, doors, piping, columns, beams and similar elements.
   
 1.1.2  Bim Assemblies
   BIM objects can be grouped into assemblies to allow for reuse of common groupings of physical elements.

 

   1.2 Proprietary and generic BIM objects
This sub-section of the standard discusses the differences between proprietary (manufacturer) BIM objects and generic BIM objects.
 1.2.1  Object type
   The object shall be modelled as a generic object or a proprietary object.
   
 1.2.2  Generic objects
   Generic objects shall be, as a minimum, recognisable as a representation of the physical element that it is representing.
   
 1.2.3  Proprietary objects
   Proprietary objects shall be an appropriate geometric representation of the physical element with accurate critical dimensions and metadata.
 
 
 1.2.4  Project objects

 Project objects are unique project-specific objects created as either a generic or proprietary object for use in a project and not intended for inclusion in a shared library.
