Tiefbau Element - Typ

An IfcCivilElementType is used to define an element specification of an element used within civil engineering works. Civil element types include for different types of element that may be used to represent information for construction works external to a building. IfcCivilElementType's may include:

The specification of the specific types is provided by the inherited attribute IfcElementType.ElementType given as an IfcLabel.

NOTE  This is due to the range of choices of element type that are available and their expression in different languages. It is not considered possible to create a reasonably full list of types within an enumeration. It is suggested that selection of the relevant type be drawn from an available 'feature catalog'.
NOTE  The IfcCivilElementType has been intruduced as a stub for future extensions of this specification to include an object model for civil engineering works.
