International Journal of Architectural Heritage [2583-3278(e)] is a peer-reviewed hybrid open-access journal launched in 2015 that promotes architectural representation through the creation of virtual 3D complex models. These models must contain not only dimensional and geometrical building aspects, but also architectural and constructive ones, describe transformations, and serve as a core for the aggregation, organization, analysis, and management of the vast and heterogeneous number of information associated with an architectural heritage – such as surveying and design drawings, historical documents, and scientific data. Many researchers have become interested in cultural heritage digital representation in recent years, with a particular emphasis on computing issues, often without distinguishing between cultural and architectural heritage. Architecture is a complex organism, a synthesis of spaces, surfaces, volumes, and materials created with specific structural systems, the result of transformation and modification processes over time, the expression of interventions, and architectural cultures that have occurred since its construction to the present day.
