Immersive real-time visualisation of complex product models has become widely used for design review within the engineering domain. In recent years a range of different VR applications have been developed for the purposes of design review and analysis. The typical data source for a review session of complex models using VR technologies is an underlying 3D-CAD system or 3D styling tool, that provides geometric and topological information of the digital model. Most of the CAD models contain digital information which is redundnt for the purposes of a VR environment. Neverthelless, the pre-processing and data preparation step is time consuming and error prone. Tedious manual data preparation and correction is still widespread and seek sfficient mecanis to automate the turn around cycles of CAD to VR sessions. Hence, we describe an efficient methodology and architecture to automate the process of data preparation for the purposes of a design review in VR.
