Freehand Drawings versus CAD Drawings in the Conceptual Architectural Design Phase

Recognition and Modeling of Architectural Objects from Architectural CAD Drawings

Recently in the eld of building CAD, research and development in CAD and data sharing among CAD tools has introduced object-oriented technology. This technology has brought object-oriented CAD tools that allow users to designing buildings by means of architectural objects and the standard data speci cation IFC (Industry Foundation Classes), which is involved in the architectural CALS (Commerce ...

Exploration through drawings in the conceptual stages of product design

This paper argues that sequences of exploratory drawings constructed by designer’s movements and decisions trace systematic and logical paths from ideas to designs. This argument has three parts. First, sequences of exploratory sketches produced by product designers, against the same task specification, are analyzed in terms of the cognitive categories of reinterpretation, emergence and abstrac...

ArchiDNA: An interactive system for creating 2D and 3D conceptual drawings in architectural design

We present an interactive system called ArchiDNA for creating 2D and 3D conceptual drawings in architectural design. We developed a novel principle of shape generation called match-and-attach by analyzing drawing styles of a contemporary architect, Peter Eisenman. The process consists of user interaction techniques and a set of rules that decide how one ormore shapes attach to another shape. On...
