A diagrammatic approach to the semantics of OO modelling notations is proposed. This is based on an innovative and expressive notation dubbed ''constraint diagrams'', which can be used to precisely characterise a range of sophisticated, static constraints on OO models. Other notations, such as those found in UML, can be viewed as projections of constraint diagrams. Work on using constraint diagrams at the core of a 3D modelling notation is also briefly described as a means of similarly providing the semantics of diagrams imposing constraints on dynamic behaviour.
