Industrial Relevance of Device Modelling,et expressed in the mixed terminology of classical line geometry and modern screw theory. This begins at §12.05. I try next, beginning at §12.14, to summarize the imaginative steps that one might take to encompass in the mind’s eye the logic of the design argument. This second theme might be said to
