Building geometric models with hand-drawn sketches

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1998.Includes bibliographical references (p. 49-51).Architects work on drawings and models, not buildings. Today, in many architectural practices, drawings and models are produced in digital format using Computer-aided Design (CAD) tools. Unquestionably, digital media have changed the way in which many architects perform their day to day activities. But these changes have been limited to the more prosaic aspects of practice. To be sure, CAD systems have made the daily operations of many design offices more efficient; nevertheless, they have been of little use - and indeed are often a hindrance - in situations where the task at hand is more conjectural and speculative in nature, as it is during the early stages of a project. Well-intentioned efforts to insinuate CAD into these aspects of practice have only served to reveal the incongruities between the demands of designer and the configuration of the available tools. One of the chief attributes of design practice is that it is action performed at a distance through the agency of representations. This fundamental trait implies that we have to understand how computers help architects describe buildings if we are to understand how they might help architects design buildings. As obvious as this claim might seem, CAD programs can be almost universally characterized by a tacit denigration of visual representation. In this thesis, I examine properties of design drawings that make them useful to architects. I go on to describe a computer program that I have written that allows a designer to build geometric models using freehand sketches. This program illustrates that it is possible to design a software tool in a way that profits from, rather than negates, the power of visual representations.by Ewan E. Branda.M.S

Design: One, but in different forms

This overview paper defends an augmented cognitively oriented generic-design hypothesis: there are both significant similarities between the design activities implemented in different situations and crucial differences between these and other cognitive activities; yet, characteristics of a design situation (related to the design process, the designers, and the artefact) introduce specificities in the corresponding cognitive activities and structures that are used, and in the resulting designs. We thus augment the classical generic-design hypothesis with that of different forms of designing. We review the data available in the cognitive design research literature and propose a series of candidates underlying such forms of design, outlining a number of directions requiring further elaboration

The Grid Sketcher: An AutoCad-based tool for conceptual design processes

Sketching with pencil and paper is reminiscent of the varied, rich, and loosely defined formal processes associated with conceptual design. Architects actively engage such creative paradigms in their exploration and development of conceptual design solutions. The Grid Sketcher, as a conceptual sketching tool, presents one possible computer implementation for enhancing and supporting these processes. It effectively demonstrates the facility with which current technology and the computing environment can enhance and simulate sketching intents and expectations; Typically with respect to design, the position taken is that the two are virtually void of any fundamental commonality. A designer\u27s thoughts are intuitive, at times irrational, and rarely follow consistently identifiable patterns. Conversely, computing requires predictability in just these endeavors. The computing environment, as commonly defined, can not reasonably expect to mimic the typically human domain of creative design. In this context, this thesis accentuates the computer\u27s role as a form generator as opposed to a form evaluator. The computer, under the influence of certain contextual parameters can, however, provide the designer with a rich and elegant set of forms that respond through algorithmics to the designer\u27s creative intents.

Emergent pedagogies in design research education

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1997.Includes bibliographical references (leaves 63-64).Recent demand for applied knowledge within architectural practice has resulted in the proliferation of university based research groups. Given the role advanced degree programs play in educating architectural researchers, an opportunity exists to educate architects towards bridging the traditional gap between practice and academia, as well as addressing the dichotomy of research and teaching within the university. Traditionally, research methods from other disciplines are taught in an attempt to redress the research deficiencies of a professional education. This investigation begins with a different premise: the operations of design, central to an architect's intellectual and operational repertoire, should be the catalyst for developing research methods specific to architecture. Further, these methods should be accompanied by a knowledge base which expresses the operations of design. A modified educational paradigm consisting of methods, knowledge, and the building of abilities through 'thoughtful performances', structures an experimental curriculum. Each attribute becomes a dimension for substantiation and assessment. Student engagement and entanglement within this locus reveals the potential directions of design research education. The subsequent analyses of the student work indicates four major trends: Intersubjectivity the need for common understanding; Transparency- the effortless application of methods, Emergence- acknowledgment of form's evolution; and Apprentissage- French for learning which occurs from within apprenticeship. Given these attributes, and the subsequent imperative to redefine architectural research, we formulate a paradigmatic architectural researcher, the "Architect Scholar' and speculate on an educational program designed to foster these characteristics within students.by Joseph Press.M.S
