Widely adopted in research, education, cultural dissemination, and media, these technologies still lack standardized methodologies and terminology. Addressing this gap, the Erasmus Plus project CoVHer (Computer-based Visualization of Architectural Cultural Heritage, 2022-2025) brought together seven partners from five European countries to establish shared guidelines, a glossary, an open-access 3D repository, and a dedicated MOOC. This panel promotes interdisciplinary discussion on the conceptual, methodological, and epistemological challenges of virtual hypothetical reconstructions. Topics include classification of digital modelling methods, representation of uncertainty, scientific transparency vs. visual conventions, and the development of a shared vocabulary for heritage reconstruction practices. The aim is to advance informed, validated, and reusable digital models that support education, communication, and cultural heritage management.Attribution 4.0 International License10.2312/dh.202533522 pages
