In mechanical engineering, instructions for manufacturing, assembly or stacking are still mostly given in 2D technical documentation. 3D modellers have enabled us to develop more complex and sophisticated products in a shorter development time. On the other hand, the manufacturing, use and maintenance phases of products are still very much based on 2D documentation, although the development of smart glasses has increased the popularity of augmented reality in industry. In this thesis, we investigated existing tools that could be used to transfer 3D models into augmented reality. We compared the supported file notations in terms of the amount of information (geometry, appearance, scene) to be transferred and found that the best notation is .fbx, followed by .obj. We have found that markers help us to position our models more accurately. Using the Vuforia web platform we tested 3 different markers. We evaluated the markers according to their characteristics such as contrast, pattern reproducibility, notation and feature richness.
