# 6.1.2.11 IfcDoorTypeOperationEnum

## 6.1.2.11.1 Semantic definition

This enumeration defines the basic ways to describe how an IfcDoor or IfcDoorType operate, as shown in Figure 1. It combines the partitioning of the access barrier into single or multiple panels and the operation types of those panels.

In the most common case of swinging doors the IfcDoorTypeOperationEnum defined the hinge side (left hung 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

Note that:

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.
