Class Documentation

class Ifc4::IfcRelVoidsElement : public Ifc4::IfcRelDecomposes

IfcRelVoidsElement is an objectified relationship between a building element and one opening element that creates a void in the element. It is a one-to-one relationship. This relationship implies a Boolean operation of subtraction between the geometric bodies of the element and the opening.

As shown in Figure 50, the insertion of a void into a wall is represented by the relationship IfcRelVoidsElement. The opening is created within the wall by IfcWall(StandardCase) o IfcRelVoidsElement o IfcOpeningElement.
