IfcWall
What is IfcWall?
IfcWall represents a vertical construction element that bounds or subdivides spaces. Walls are one of the most fundamental building elements in any IFC model, defining the physical envelope and internal partitioning of a building. IfcWall can represent both load-bearing structural walls and non-load-bearing partitions.

Real-World Usage
Walls define rooms, building envelopes, and fire compartments. In construction, tracking wall elements helps manage material quantities, installation progress, and compliance with thermal and acoustic regulations.

IfcCurtainWall
IfcCurtainWall represents a non-load-bearing exterior wall system that is hung from the building structure, typically consisting of a metal frame with glass, metal, or stone panel infill. Curtain walls carry only their own weight and wind loads, transferring these to the primary structure at each floor.
Building ElementIfcColumn
IfcColumn represents a vertical structural member that transmits loads from beams and slabs to the foundation. Columns are key elements in the structural grid of a building and can be made of concrete, steel, timber, or composite materials.
Building ElementIfcSlab
IfcSlab represents a horizontal construction element that forms the floor, roof, or landing of a building. Slabs can be classified as floor slabs, roof slabs, landing slabs, or base slabs (foundations). They are typically the largest elements by area in a building model.
Building ElementIfcDoor
IfcDoor represents a construction element that is used to close an opening in a wall or partition. Doors provide access between spaces and carry properties about their operation type (single swing, double swing, sliding, revolving), fire rating, and accessibility compliance.
Building ElementIfcWindow
IfcWindow represents a construction element placed in a wall opening to allow light and ventilation. Windows carry properties about their glazing type, thermal performance, operation type (fixed, casement, sliding), and dimensions.
Opening ElementIfcOpeningElement
IfcOpeningElement represents a void or hole cut through a building element such as a wall, slab, or roof. Openings are used to accommodate doors, windows, ducts, pipes, and other penetrations. The opening itself is a subtractive element — it defines the shape to be removed from its host element.
