What is 3D SKETCHING?

The question is: Since we live in a three-dimensional environment, why ideas and concepts are expressed in a bi-dimensional paper sheet? Think about it, it makes no sense! A flat x,y axis universe could be good for the Simpsons or the Griffins but I used to live in the real world and a sketchbook is not enough to express the flow of my creativity. I’m no painter, my task is to conceive complex multifaceted objects, evaluate their proportions, volumes and capacity from the very first stage of the creative process. Pencil’s lines, light and shade effects on paper are romantic but if it’s true that a photo is worth a thousand words, A REAL MODEL IS WORTH A THOUSAND PICS. Now, we’re not talking about 3D cad and rapid prototyping models: they are part of the final design stage, right before production. Cad models are complex digital entities, outcomes of computers, sequences of numbers, food for CNC machines. 3D sketching is CONVEYING AN IDEA TO THE REAL ENVIRONMENT, pencil’s lines are intangible and questionable, solid sketching is A QUICK TOUCHABLE REPRESENTATION OF WHAT I’M THINKING, like pouring ideas  from my mind straight to a metal frame which volume is easily measurable. Pay attention, this is neither carving nor sculpturing a stock, this is filling the space with thin iron lines, so the big difference between 3d sketching and 3D modelling is that the first is a craftsman operation that get the design process started, the second is the last engineering stage before pilot production.
