Ken,
As you know from your experience is that designing with computers has this unique and very fast method of collaboration and sharing of design concepts and thoughts. This being just one of the significant advantages to designing with CAD over the antiquated previous paper and pencil methods of visualizing design. I too was taught design on the board often working with paper or cloth and ink pens. Sure looked nice when done but the time and possibility for revisions and improvement seriously limited.
Concerning the design and easing of edges, there are no sharp edges, any sharp edge is eased with a purposed chamfer. Not rounded edges often caused by polishing over a egde which is not very nice looking but intended and carefully cut or filed on. My plan has always been to chamfer the edge in question. I am doing that now and when polished I will take new pics and post them. If we do not like the chamfer I am always steel safe to change to a radii but that is part of design and the tweaking there of.
