In recent years we have been experiencing an ever-increasing number of Building Modeling Modeling (BIM) and Visual Programming Language (VPL) approaches in the architectural design field. These experiments have inspired new research strictly focused on exploring values, criticalities, and the advantages of applying these combined methodologies in the Cultural Heritage domain. This integrated approach has emphasized the benefits derived from HBIM. The next step is to critically evaluate the application of BIM and VPL processes used in the management and valorisation of museum heritage, pursuing both parametric and algorithmic approaches. The research group worked on building a model that shared the BIM hierarchical structure and the flexibility of the VPL methodologies. Semi-automatic procedures were developed within a rigorous BIM workflow, with the help of Autodesk and McNeel tools, to show and manage complex museum management phenomena. These procedures aimed to respond to three different objectives. First, the need to associate information from the Facility Report to the individual BIM components to predict and monitor the conditions in which museum collections are found. Second, the intention to measure the attractiveness of the artifacts within the exhibition project and the design effects for a correct prefiguration of visitor flows. Third, the elements involved included the exhibition area obtained from an HBIM model (converted into a visual field through interoperable processes), the digitized collections (the attractive elements), the users and, finally, the numerical evaluation of the visibility of specific objects within collections by simulating the human point of view. Once automated, the devised procedures can be considered a prototype to support curators in controlling and improving the efficiency of the exhibition layout.

This contribution explores the application of the BIM methodology in the context of built heritage (HBIM). Specifically, it investigates how this methodology has evolved in terms of modeling techniques, viewed through the lens of Drawing as a critical aspect of its implementation. By considering these perspectives together, the paper aims to identify the primary advantages and limitations of HBIM, highlighting the need for defined workflows to effectively manage and deconstruct the intricate architectural elements found in the Palazzo del Collegio dei Nobili, which represents Turin's brick buildings from the Savoy Baroque period.

One of the main themes of this work is to incorporate the geometric aspects that characterize a certain type of architecture within a broader rule system, which, in the whole, generate the forms. Therefore, the solution would be to draw the reconstruction of a parametric model, through the application to a selected case study: Palazzo del Lavoro of Pier Luigi Nervi. The identification of some weaknesses of the project is important in order to digitally intervene on them, to prefigure a new life of the artifact in a virtual environment. By doing so, it will be possible to have truthful feedback in the real environment. The survey phase did not intend to reason on the architecture in its complexity, but rather on the observation of the matrices that regulate the similar geometries between them. The translation of these matrices into mathematical models, following the logic of HBIM and Algorithmic Design (AD), has allowed the creation of two different models. The first one, an informed model, characterized by a more traditional workflow, consists of building components based on design drawings of the time, aimed at graphically and quantitatively describe the entire artifact. The second one, a partial model of the only vertical component of the facade, is based on the canons of the element, and it is structured through algorithms that describe only a part of the architecture. The research wanted to deepen the interoperability of the information coming from the parametric models BIM with those generated by the algorithms.

An approach to digitally model the decorative elements window’s of architectural heritage—the College of Nobles, Turin—in HBIM, by applying De Luca’s method. The strategy is to transform them into mathematical ratios and parameters in order to create flexible and adaptable models that can generate variations.
