Returns the value of OverallHeight attribute. This attribute represents overall measure of the height, it reflects the Z Dimension of a bounding box, enclosing the body of the door opening. If omitted, the OverallHeight should be taken from the geometric representation of the IfcOpening in which the door is inserted.

Returns the value of OverallHeight attribute.

The body of the door might be taller then the door opening (e.g. in cases where the door lining includes a casing). In these cases the OverallHeight is still specified as the door opening height, and not as the total height of the door lining.
