By Karim Hadjri


The advance of technology in the areas of building, environmental control and computing, meant that architectural teaching processes needed to adapt to the increasing use of modern tools. However, in may schools of architecture, computer technology is not adequately integrated into the curriculum, because first, its introduction means that there is a need for an important change in the way architectural design is taught particularly in studios, and then, the learning outcomes of digital modelling are not known or understood. Not surprisingly, digital technology is allowing students and designers to explore new areas without restraining their imagination in order to produce buildable complex designs such as Frank Gehry’s work. The process by which this is achieved relies primarily on the use of “hybrid ” design techniques; i.e. the making of scaled physical models, followed by 3-Dimensional digitisation, and then 3D modelling. Traditionally, students produce very accurate scaled physical models as part of their design development, but struggle to recreate them digitally for further analysis and improvement. This paper presents a recent experience related to the introduction of a new course on 3D digitisation and modelling. This was done with the aim to bridge the gap between physical and digital models produced by students as part of their design development exercise. A preliminary research into scanning and digitisation methods including Photogrammetry was necessary in order to assess their suitability to the project requirements. This resulted in the production of a course unit addressing the different scanning and digitisation methods available. The objective of the course was to effectively use a tracking device (Microscribe 3D) to digitise complex physical models, and therefore create very accurate digital copies. Digital models were then improved to allow an understanding of the design- space, form, materials and light- throug
