My big parametric drawings usually start with a smaller scale study drawing that is about a twenty-five percent scale to the eventual big drawing. One might think that the large drawing will look identical to the smaller scale sketch drawing. It never does. I always change things. Make adjustments. Usually adding more patterns, repetitions, and complexity.
Shown here is a very simplified case of study vs full-size drawing as this is one of my least complicated drawings. The images are in approximate scale to one another.
