6.4.3.7 IfcSystemFurnitureElementType

6.4.3.7.1 Semantic definition

The furnishing element type IfcSystemFurnitureElementType defines commonly shared information for occurrences of system furniture elements. 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 system furniture element type specification indicating the specific product information that is common to all occurrences of that product type. The IfcSystemFurnitureElementType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcSystemFurnitureElementType are represented by instances of IfcSystemFurnitureElement. Refer to the documentation at IfcSystemFurnitureElement for supported property sets, materials, and composition.
