Abstract: In theory, the potential to use virtual reality systems for creating visually rich and free-spirited models and prototypes is high. In contrast, immersive modelling is not relevant in today's design practice and design researchers are often sceptical if it will ever be possible to use virtual environments (i.e. virtual material) with the same fidelity as physical materials. The aim of this paper is to search for bridges which allow designers to use the potential of immersive modelling even though no materiality (i.e. no touchable material) is present. It describes four approaches of mastering digital materiality which emerged during a design study among four design students who used an immersive modelling system for two weeks all day long. All approaches imply different means of substituting the missing material constraints. Furthermore the results of a post-study survey among the participants are discussed. The results of this study suggest that designers can find individual ways to handle digital material in immersive environments which may satisfy their professional expectations and standards. They may possibly be able to develop a professional level of manipulative skills within virtual environments comparable to their work with physical material. It can be expected that more approaches to immersive modelling appear as the technology advances and designers become engaged with it.
