Abstract
The growing interest within the construction industry in the preservation, rehabilitation, and conversion of heritage-value buildings has led to the implementation of Historic Building Information Modelling (HBIM) across all sectors. The rigorously accurate representation of old construction solutions for roofs, floors, and walls, and of the decorative details and finishes, commonly used in historic buildings of patrimonial value, requires specific geometric modelling processes in order to generate relevant libraries of parametric objects. This study addresses the generation of parametric families of representative architectural geometry in the context of the conversion of a building of patrimonial value. A collection of historical information and a detailed inspection in situ, recorded by means of digital images and sketches with annotative dimensions of the architectural forms, were first carried out to support the accurate representation of the building. Several families of objects were generated, namely, guillotine windows, glazed doors, ornamental stonework, staircases, and handrails, thus creating a reference library for use in further similar building projects. The study improves the potential of the BIM process for its application to buildings with distinctive architecture in the context of the preservation or conversion of heritage buildings.

Summary
The Building Information Modelling (BIM) methodology provides the ability to visualise the three-dimensional (3D) geometric model of a building, and considers the generation, updating, and re-use of all of the information associated with the project, centralised within a digital model [1]. The generation of a BIM model representing a historical or heritage building may be considered as contributing an important collaborative platform; for this purpose, the model must include all of the information required by those specialist professionals. For a rigorously accurate representation of the architectural geometry and the construction solutions adopted in historic buildings, the libraries of parametric objects available in the most used BIM-based modelling systems are very limited. The present text describes the modelling component of an academic research paper concerning the elaboration of a proposal for the refurbishment of a building of patrimonial value located in Lisbon, Portugal [9] This required an initial task of document collection, followed by a detailed modelling process to generate rigorously accurate geometric forms of elements, such as walls, floors, roofs, windows, doors, staircases, and handrails. The main objective of this work was to generate a library of parametric object families to be used in the selected case study and, eventually, in other similar buildings of the same epoch with an aristocratic characteristic
