Generally for any new design initially a concept layout in 2D CAD is generated. But sometimes if the geometry of product becomes complicated, then 3D CAD model is preferred. Because 3D CAD model can give us a complete all side view at a time like a real product, but in a virtual world. The present case study will show the utilization of 3D CAD at the concept design stage of a complicated shaped product for a new system. This will also give an idea about cost and time comparison. Thus this paper will describe about the importance of 3D CAD tools for product development.
