I always try to visualize feature grading of a hole when I lay it out on paper - from nothing to some corrective grading that may be necessary.
I agree that field time, i.e., hand waving, is important, but gradiing plans and cut/fill calculations are essential - to me at least - in getting the basics down. I have never laid out a green in the field only w/o it coming out too small, for instance.
With computer 3-D graphics now, the architect, and shaper can better visualize the intent, although, we can't seem to get really subtle nuances in 3-D, at least yet.
I'm not sure shapers make the real good architects famous. They are more likely to "save" an architect who really doesn't know what he/she wants, usually either early in the career, or through plain lack of creative vision, or a personality that is afraid to take chances.
