Among the many cases that concern the process of digital hypothetical 3D reconstruction a particular case is constituted by never realized projects and plans. They constitute projects thought and remained on paper that, albeit documented by technical drawings, they pose the typical problems that are common to all other cases. From 3D reconstructions of transformed architectures, to destroyed/lost buildings and part of towns.
This case studies start from original old drawings which has to be implemented by different kind of documentary sources, able to provide – by means evidence, induction, deduction, analogy – information characterized by different level of uncertainty and related different level of accuracy.
All methods adopted in a digital hypothetical 3D reconstruction process show us that the goal of all researchers is to be able to make explicit, or at least intelligible, through a graphical system a synthetic/communicative level representative or the value of the reconstructive process that is behind a particular result.
The result of a reconstructive process acts in the definition of three areas intimately related one each other which concur to define the digital consistency of the artifact object of study: Shape (geometry, size, spatial position); Appearance (surface features); Constitutive elements (physical form, stratification of building/manufacturing systems).
The paper, within a general framework aimed to use 3D models as a means to document and communicate the shape and appearance of never built architecture, as well as to depict temporal correspondence and to allow the traceability of uncertainty and accuracy that characterizes each reconstructed element.
Case studies span from Palladio to Ledoux, from Antolini to Jefferson.
