Knowledge discovery and data mining techniques have the potential to find patterns in very large sets of data. Applying these techniques to design data has two problems: the volume and complexity of the source data, and the discovered knowledge itself. A result is that existing algorithms may not be computationally feasible and in any case may not produce, of themselves, results that are of int...

Collaborative AEC technologies centering around component-based CAD models support architectural and structural perspectives. The construction perspective is often neglected because an important dimension for construction—time—is missing. Construction planners are forced to abstract CAD model building components into schedule models representing time. 4D-CAD (3D-CAD + time) removes this abstrac...

327 The problems of architectural education in general and CAD education in particular are discussed. The paper suggests that the computing requirements of architectural practice are different to those of architectural education and that much of the software used in schools of architecture is not used in an educationally structured way. A number of proposals for the educational use of computers...

Screening mammograms is a repetitive task that causes fatigue and eye strain. For thousands of cases analyzed by a radiologist, not more than ten are cancerous and thus an abnormality may be overlooked. Computer-aided detection (CAD) algorithms are developed to assist radiologists in detecting mammographic abnormalities. In this paper, a CAD system is developed to classify Architectural Distort...

In Computer Aided Architectural Design, digital design is becoming an increasingly important process. The large number of recent articles about pure digital design cases (i.e., with only one CAD-package) is an indication of the demand for the utilisation of CAD-software advantages in the architectural design process. In most of these digital design cases there is no proper design environment si...

This paper describes how we could combine the two most available systems for the purpose of surveying and documenting the architectural heritage, historical buildings and monuments. The two systems are digital photogrammetry (applied in a close-range context) and CAD. The product of this integration is a 3-D GIS application. In this application, close-range photogrammetry is used for the acquis...

This paper presents a method for IFC-compliant design information modelling and sharing by use of the IFC technology and IFC property set (Pset) extension mechanism. The method comprises defining the nonstandard and project-specific design information in extensible and interoperable Psets, instantiating these Pset definitions with CAD object information and generating IFC-compliant product mode...
