6.4.3.3 IfcFurnitureType

6.4.3.3.1 Semantic definition

The furnishing element type IfcFurnitureType defines commonly shared information for occurrences of furnitures. The set of shared information may include:

  • common properties with shared property sets
  • common representations
  • common materials
  • common composition of elements

It is used to define a furniture type specification indicating the specific product information that is common to all occurrences of that product type. The IfcFurnitureType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcFurnitureType are represented by instances of IfcFurniture. Refer to the documentation at IfcFurniture for supported property sets, materials, and composition.
