Interactive 3D visualization to facilitate understanding of assemblies and details in construction education

Perdomo, J.L., Shiratuddin, M.F., Thabet, W. and Ananth, A. (2004) Interactive 3D visualization to facilitate understanding of assemblies and details in construction education. In: ASEE Southeastern Section Conference, 4 - 6 April, Auburn, Alabama



Throughout the years, various teaching methods have been adopted to assist students to better understand building assemblies and construction details. Many current teaching techniques to explain assemblies, components and their sequence of construction rely heavily on traditional instruments such as 2D CAD drawings, photographs and site visits. These techniques have their own drawbacks. However, 3D CAD modeling addresses the third dimension that is not present in 2D CAD drawings, that is allowing better viewing, validating and understanding building components and their construction. This paper addresses the impact of understanding 3D and its advantages over current approaches. The paper describes a pilot study conducted with students from the Virginia Tech Architecture and Building Construction departments. The experiment investigated the advantages of 3D representation as compared to 2D drawings, in understanding construction assemblies and details. The paper also discusses the shortcomings of the traditional methods and compares the suitability of using 3D as a teaching aid. A new approach utilizing Pocket PCs via wireless connectivity, to allow students access to and viewing of 3D models remotely, is briefly presented.
