Abstract This work explores the integration of Extended Reality technologies into the field of modeling, focusing on the placement of digital models created off-site in their respective real-world environments on-site. While traditional modeling platforms like ADOxx operate in 2D environments, the M2AR modeling platform offers 3D modeling capabilities using WebXR and Three.js, enabling cross-device compatibility through web-based access. A key challenge addressed in this work is anchoring digital models to their corresponding real-world locations. To this end, three conceptual solutions were proposed. While Conceptual Solution 1 relies primarily on manual user input, Conceptual Solution 2 enhances this approach by integrating GNSS location data for improved guidance. Conceptual Solution 3 employs mostly automated approaches through the use of computer vision algorithms for location recognition and model placement. However, due to technical constraints, only Conceptual Solution 1 was implemented in this work. The implementation was tested across six diverse real-world locations and demonstrated functional usability for AR model placement using 3D images. While the approach proved effective in real-world environments with clear depth cues, it exhibited limitations in large open spaces or when dealing with flat or distant structures. 80% of the defined requirements were fully met. The solution’s capability to address the problem was successfully validated within the M2AR modeling platform.
