Augmented Reality (AR) and Virtual Reality (VR) play an important role for the implementation of Industry 4.0 - especially in the area of virtual prototyping, manufacturing and maintenance. Thus, a holistic integration of these technologies in existing processes structures is essential to ensure future competitiveness of companies. Current research mostly focuses on some aspects of the lifecycle and not on the whole process. Furthermore, mostly specific tools are developed to create AR and VR contents instead of using already existing and widespread programs for example the 3D CAD software Inventor  or game engines like Unity . The tools are used to create VR content providing a user-friendly environment with limited options for content creation. On one side the use of these programs decreases the required knowledge to create Mixed Reality applications, however they are associated with high implementation and running costs. This increases the entry barrier for small and medium sized enterprises (SME) to adopt AR and VR into their value chains significantly.
The presented work discusses concepts and proposes information models for adding VR-specific information directly in CAD environments. A generic model of necessary interaction options as well as VR properties is created and applied to a use case in the Industry 4.0 model factory at FH Aachen, Germany. Furthermore, a workflow for combined evaluation of product and equipment developments is developed focusing on VR integration.
