This thesis presents the development and use of "HoloFactory", an application that aims to facilitate the design and layout of industrial production lines through the use of Virtual Reality (VR). This project leverages the immersive capabilities of Head Mounted Displays (HMDs) and hand-held Motion Controllers to provide a comprehensive tool for building industrial environments in a virtual space. The project was carried out in collaboration with SEICA S.p.A., a company specialized in the development and production of automatic test equipment for electronic components and electric batteries. The main focus of this project is to provide an effective and intuitive alternative to traditional CAD tools for planning and layout activities.
