1999: Product-based Model Representation for Integrating 3d Cad with Computer Simulation
نویسندگان
چکیده
Computer-Aided Design (CAD) is widely used during the engineering design stage of construction projects. CAD generally contains a wealth of information regarding the facility to be constructed; this information can be effectively used for construction decision-making. This paper undertakes an investigation of the possibility of using a “product-based” model representation for integrating 3D CAD with computer simulation to facilitate better decision-making during construction. The objective is to conceptualize an environment that allows an engineer to specify how construction of the facility will be carried out with CAD. The environment could then extract relevant information to produce simulation models that will enable better understanding of the construction process, better estimating of cost, and more appropriate planning.
