More so, some cad software allows you to analyse product before manufacturing. Giving you insight on what works and what won't. Meaning you are in control right from the start. Hence, eliminating waste resulting from failed untested product, cut unnecessary labor cost and also reduce stress related to product development failure.
To make 3D cad model, your first step is to give thought to your concept. Followed by putting design concept on paper in the form of sketches, then add dimensions to different geometry of the design. Get a cad software such as AutoCad, Autodesk Inventor, Solidworks, Catia , proE and many more, then go to work.
Let say you want to make a 3D model like this image.
