How do the CAD images differ from what the finished piece will look like?

Computer "renderings" generated from the CAD file are quite realistic, but there are important subtle differences between these images and what you will see when the piece is finished. The primary difference is that the program file includes extra metal that will necessarily be removed in the finishing and polishing steps. Therefore prongs look longer, edges sharper and the piece is overall a bit bulkier than it will be when finished.
