6.1.2.10 IfcDoorTypeOperationEnum

This enumeration defines the basic ways to describe how doors operate, as shown in Figure 156. It combines the partitioning of the door into a single or multiple door panels and the operation types of that panels.

In the most common case of swinging doors the IfcDoorTypeOperationEnum defined the hinge side (left hing or right hung) and the opening direction (opening to the left, opening to the right). Whether the door opens inwards or outwards is determined by the local coordinate system of the IfcDoor, or IfcDoorStandardCase.

NOTE  There are different definitions in various countries on what a left opening or left hung or left swing door is (same for right). Therefore the IFC definition terms may derivate from the local standard and may need to be mapped appropriately.
HISTORY  New Enumeration in IFC4.
IFC4 CHANGE  The new IfcDoorTypeOperationEnum replaces the use of IfcDoorStyleOperationEnum that is deprecated from IFC4 onwards.

Enumerated Item Definitions:

Enumerator Description Figures  
SINGLE_SWING_LEFT Door with one panel that opens (swings) to the left. The hinges are on the left side as viewed in the direction of the positive y-axis.
NOTE  Direction of swing (whether in or out) is determined at the IfcDoor or IfcDoorStandardCase.

SINGLE_SWING_RIGHT Door with one panel that opens (swings) to the right. The hinges are on the right side as viewed in the direction of the positive y-axis.
NOTE  Direction of swing (whether in or out) is determined at the IfcDoor or IfcDoorStandardCase.

DOUBLE_DOOR_FOLDING Door with two panels, one is folding to the left the other is folding to the right. double folding double folding
REVOLVING An entrance door consisting of four leaves set in a form of a cross and revolving around a central vertical axis (the four panels are described by a single IfcDoor panel property). revolving   
ROLLINGUP Door that opens by rolling up.
NOTE  Whether it rolls up to the inside or outside is determined at the IfcDoor.
rolling rolling
SWING_FIXED_LEFT Door with one panel that opens (swings) to the left and one fixed panel. The hinges of the swinging panel are on the left side as viewed in the direction of the positive y-axis.
NOTE  Direction of swing (whether in or out) is determined at the IfcDoor or or IfcDoorStandardCase.
IFC4 CHANGE This is a new enumerator compared with previous IfcDoorStyleOperationEnum.<

SWING_FIXED_RIGHT Door with one panel that opens (swings) to the right and one fixed panel. The hinges of the swinging panel are on the right side as viewed in the direction of the positive y-axis.
NOTE  Direction of swing (whether in or out) is determined at the IfcDoor or or IfcDoorStandardCase.
IFC4 CHANGE This is a new enumerator compared with previous IfcDoorStyleOperationEnum.
swinging right and fixed swinging right and fixed
USERDEFINED User defined operation type    
NOTDEFINED A door with a not defined operation type is considered as a door with a lining, but no panels. It is thereby always open. not defined

NOTE

  1. Figures are shown in the ground view.
  2. Figures (symbolic representation) depend on the national building code.
  3. These figures are only shown as illustrations, the actual representation in the ground view might differ.
  4. Open to the outside is declared as open into the direction of the positive y-axis, determined by the ObjectPlacement at IfcDoor
  5. The location of the panel relative to the wall thickness is defined by the ObjectPlacement at IfcDoor, and the IfcDoorLiningProperties.LiningOffset parameter.
