Regarding the utilization of state-of-the-art IT in the building industry, adherence is still very poor. Most established developments are concentrated on the Computer-Aided Design (CAD), drafting, scheduling control of tasks, and automation of certain pre-fabrication processes. Each application very often runs alone, without the capability to exchange the necessary data automatically. This situation has driven companies to reach proprietary dependent departmental solutions, without a complete integration of product, process and business data. 

Part modeling is the historical area of computer aided design, drafting, and manufacturing. Traditionally, part models were constructed individually and each part model was stored in a separate file. Now, five different aspects integrate part modeling in a comprehensive product modeling environment. They are ... 

As an aid in determining the severity of vapor cloud explosions, overpressure radius circles are normally plotted on a plot plan from the source of leakage or ignition. Computer applications are available that can easily calculate and plot these on electronic plant design and drafting applications. These overpressure circles can be determined at the levels at which destructive damage may occur to the facility from the worst case credible event (WCCE).

Modern CAD—an acronym for computer-aided drafting or design—has its roots in the early 1960s. Aerospace, automotive, and electronics companies first used CAD. These large companies were the only ones who could afford computers that could perform the massive calculations needed for CAD. As personal computers became affordable and CAD software became available for this size of computer, CAD became a universal application in design, manufacturing, and construction (see Figure 7-1). 

In the second half of the twentieth century, computers have enabled architects and architectural engineers to function with a greater degree of precision. Computer-aided drafting and design (GAD) software is an essential tool for architects. Computers also can be used to create simulations and animations, as well as detailed presentation graphics, tables, charts, and models, in a relatively short period of time.
