The goal image and Virtual image and final 3D scale model and of the design are shown below, a photo-realistic virtual model, detailed physical model definitely induce a sense of resolution, or finality, that discourages change, that is their purpose. (That is not to say that physical conceptual models cannot be used in design development, this is common practice. Effective but expensive and only possible where substantial skilled human, and financial resources are available)

The marine designer in dealing with qualitative form, employs an analytical methodology which, although very different process from the numerical approach, has its own validity, it is not a random and directionless process, However;
“Science and engineering on the other hand has: Canons of rationality and objectivity agreed by consensus in the scientific community for assessing scientific theories. Among them are predictive powers, degree of unification of disciplines, rigor of foundations, and agreement with conservation laws. Yet just as in any creative enterprise,
the rules of procedure are not always strictly adhered to and are sometimes set aside”. [12]
There have been many methodologies industrial
proposed for design and architecture, these often have
substantial validity yet most designers the author knows, do not follow a specific methodology although many use similar elements in their approach.
For example the author has often experienced the
apprehension of what one senses will be a total and appropriate response to a design without being able to define precisely, in any visual way, what this may be. It is believed this precursor to design or “avatar” is a common experience, one we often define as an intuition
