Computer Intelligent Design: What´s Computer Aided Design?

Computer-Aided Design (CAD) is used to help engineers and designers to create, modify and analyse graphical or geometrical designs in an optimized manner. It uses mathematical formulas to form a geometrical shape using computer software. Its revolution started early at the MIT in the mid-1960s as a result of early interest in computer graphics developed rapidly as computers became more affordable, and the application areas have gradually expanded [Sutherland, 2003].

Building up a Web-based collaborative 3D shape modelling requires a deep investigation regarding three major aspects, namely Networking, Modelling and Visualisation, problems surrounding these topics need to be discussed, resolved and solutions to be implemented. Networking concerns

Based on different available scenarios provided from different online and offline resources such as hardware changes, connection bandwidth monitoring, server stability and performance, memory consumption and availability, etc…, Scenario Optimization usually provides efficiency and accurate real time decision making depending on the continuous monitoring and tracking for the emerging changes of hardware, connection and software resources, and helps in reducing the time cost making use of the available resources [Mars and Hundt, 2009]. The scalability and availability of any environment, especially online one, depends on scenario optimization, which constitute an essential factor of

Cloud computing including virtualization and parallel computing could be one of the useful available solutions, where online big data storage and processing on demand can be applied [Wu et al, 2014]. 3D scenes are difficult to integrate in HTML files, and Web browsers are not designed to deal with large 3D data files with vast amount of computational resources. One of the available options is to develop a partially interactive and immersive flash animation from a 3D scene [Rodrigues et al., 2011]. Another option is to play back a reproduced “flat” 3D environment in the browser; such environment is composed of several pictures covering 360 degrees and stitching them together, all the above possible solutions use the internet as a transmission media to transmit information (images and data) between the environment’s servers and the
