summary	In this paper we present an environment for conceptual design which mimicsthe interaction of designers with physical mockups. We present novel three dimensional on-and-above-the-surface interactive techniques which combine asymmetric bimanual operations with multi-touch direct manipulation on a fl at surface and depth cameras. These take advantage of a continuous interaction space to create and edit 3D models in a stereoscopic environment. To allow modeling architectural shapes directly, we combine hand and finger tracking in the space above the table with multi-touch on its surface without the need to change modes. This provides an alternative design environment where users can seamlessly switch between interacting on the surface or in the space above it depending on the task, which makes it easier to model complex shapes using simple operations.

summary	A parametric urban design system integrating GIS data in a CAD environment is proposed as a platform for discussing urban plans providing flexibility and information access in an interactive fashion. The proposed system links calculations of urban indicators with the parameter manipulation of the layout geometry, therefore allowing for a systematic update of indicators according to design modifi cations. Hence, design may be fine-tuned in an informed manner enhancing the quality of design decisions.

title	An alternative Palladian shape grammar: A subdivision grammar for Palladian villas
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 415–424
doi	https://doi.org/10.52842/conf.caadria.2012.415
summary	This paper describes a shape grammar that recreates Palladio’s villas. A Palladian grammar was previously proposed by Stiny and Mitchell. However, this alternative grammar uses different parametric shape rules and methodology to test the hypothesis that different grammars can generate the same corpus of designs. The formalism is then implemented using a computerised design tool. The grammar includes subdivision rules that allow for a more economical formulation. The project is part of wider research aimed at formulating a generic housing grammar.

summary	The research presented further is part of the Digital Alberti research project, which aims to assess the infl uence of Leon Batista Alberti’s theory on Portuguese architecture, through the use of digital technologies. One of the project tasks implied computational and physical modelling of Alberti’s column system. Development of the computational model implied decoding Alberti’s treatise on architecture De re aedifi catoria into a consistent set of parameters and relationships, and then implementing these into generative parametric computer programs through visual programming language Grasshopper. This computational model is able to automatically generate physical models of classical columns according to Alberti’s canons. These digital models were then materialized through production of physical models, through rapid prototyping and digital fabrication technologies. Special attention is given to the CNC stone milling of a Corinthian capital.

title	GRAMATICA: A general 3D shape grammar interpreter targeting the mass customization of housing

summary	This paper presents a general 3D shape grammar interpreter named GRAMATICA and illustrates its use for the implementation of several shape grammars, including the one used in the design module of a specifi c shape grammar for mass-customized housing, called DESIGNA. The underlying shape representation, generation and control are discussed. The resulting shape grammar interpreter tries to support designers’ ways of thinking and working by acting as a bridge between shape grammars, the formalism that captures a design process, and a CAD application, for post-processing the computed design. This bridge is implemented by Rosetta, which ensures portability among different CAD applications.

summary	This article describes the class Alberti Digital taught at the Faculty of Architecture of the Technical University of Lisbon (FAUTL) and later in the Department of Architecture, University of Coimbra (Darq / UC), centered in interpretation and exploitation of Alberti`s treatise Da Arte Edificatoria where students had to develop a visual computer program with the algorithms present in the treatise to generate virtual and physical models using different digital fabrication techniques, allowing them to gain skills in the use of computational resources and knowledge of history and theory related with Renaissance architecture and the principles of Alberti in particular.

summary	This article focuses on the use of both shape grammar and space syntax as tools to identify and encode the principles and rules behind the adaptation of existing houses to new requirements. The idea is to use such rules as part of a transformation grammar-based methodology for the rehabilitation of existing dwellings. The developed grammar is a specifi c grammar to inform the rehabilitation of a particular type of building in Portugal – “rabo-de-bacalhau”. In this article the goal is to explore how the “rabo-the-bacalhau” transformation grammar can be transformed in a general rehabilitation grammar in order to inform the rehabilitation of various types of housing buildings.

title	Repensando a Cortiça em Arquitetura através do uso de Tecnologias CAD/CAM [Rethinking Cork in Architecture through the use of CAD/CAM Technologies]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 673-676
summary	In contemporary architecture there is a growing interest in exploring unique forms and constructive solutions, which could hardly be conceived and materialized until recently. Operating in this context, the construction industry has tried to innovate by inventing new materials aside with rethinking existent ones. In this second scenario, given that the use of CAD/CAM technologies have opened new possibilities for traditional materials, it becomes important to ask if cork could face similar innovative opportunities. The present paper synthesizes some of the main arguments, experiments and results obtained in a PhD thesis about that question.

title	Assessing Santa Marta: Using Evaluation Tools to Inform Parametric Urban Design
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 749–758
summary	Lack of affordable housing is a worldwide problem. Rapid urbanization, rural exodus, and poor governance policies have contributed to the problem and, in response, low-income populations resort to self-construction. The result are informal settlements located predominantly in marginalized urban areas (United Nations, 2015) that develop with neither urban infrastructure nor compliance with building and planning codes (Lall et al., 2006; Patel et al., 2018; United Nations Human Settlements Programme, 2012) and, consequently, offer a poor-quality built environment. The goal of this paper is to methodologically identify physical aspects of such built environments that could be improved. We evaluate a case study, the Santa Marta favela in Brazil, using a holistic housing-quality assessment tool and local building and planning codes as reference. Our results identify the physical characteristics with lower quality standards in the case study and demonstrate the efficacy of the methodology introduced for this purpose.
