White Paper Explicit 3D Modeling Page 1 of 6 Introduction Despite the growing market pressures and the advantages of 3D CAD, many companies still rely exclusively on 2D design or drafting for their design process. In fact, a recent Aberdeen Group study suggests that as many as 85% of those who design products primarily employ 2D design or drafting only. Why? Because 2D design still works. For companies with a large amount of geometry and multiple revisions of data, like those that develop specialist processing equipment for example, the challenges and risks of adding 3D modeling to their design process simply outweigh the benefi ts. With 2D design, companies know they have a functional, tested, and reliable system already in place. This paper discusses explicit modeling, an alternative approach to 3D design that offers a more palatable solution for those still working in 2D. For companies where one-off or highly customized product designs are common, explicit modeling provides less disruption to existing processes as well as a profi table, lasting addition to the business… Virtual prototypes Companies that only use 2D development often remain unaware of collision problems until they assemble a physical prototype. With 3D CAD, however, manufacturers can develop virtual prototypes in 3D space. That means manufacturers can check models for both potential problems and overall quality before making costly investments of both time and money on a physical prototype. When manufacturers investigate potential problems earlier in the design process, they can also substantially reduce the number of expensive change orders later. Fewer physical prototypes and change orders means better quality designs, shorter time to market, and lower product development costs. Extended add-on capabilities Unlike 2D CAD, 3D CAD systems offer many extended add-on capabilities for both design teams and downstream departments. For example, design teams can use the extended design capabilities to automate, innovate, and reuse or repurpose designs – all of which ultimately lead to better products, developed faster, at reduced costs. With 3D modeling, downstream departments can also work concurrently with design teams.
