  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.
  
  - Example -
  The following image shows the insertion of a void into a wall that is represented by the relationship IfcRelVoidsElement. 
  The opening is created within the wall by <em>IfcWall(StandardCase) - IfcRelVoidsElement - IfcOpeningElement.</em>
