1. Constructing Product Forms Basic Concepts in Datum, Origin, and Measurement

2. Observations We can easily recognise the product type when the RELATIONS and PROPORTIONS of the chunks are correct

3. Observations Minor details can be eliminated without affecting our form perception

4. Discussion If the previous statements are true, what is their implication on Styrofoam prototyping for form exploration?

5. Discussion Serrated silhouette with few details or simple silhouette with many details. Details group together. Internal edges aligned to one or two directions. Everything snap to an invisible ‘grid’.

6. Discussion Voids are important to composition because they create contrast. Equally spaced elements, no matter how different in shape, look similar. Shades add weight to a composition, thus should be considered together with formal elements

9. Activity – Geometrical Form Design a very simple form by combining 1 cube, 1 cubical hollow, 1 cylinders and 1 cylindrical hollow. You might give your form a purpose (e.g. vase, desk lamp, etc.) but don’t let yourself drown in the functionality, keep focus on the form Start by making a 2 blocks composition and then fine-tuning the proportion The form should be distinctive and good looking On one A4 paper, draw at least 6 perspective view of your design from different angle, apply colour shading to your views, maintain consistence between views + = ?
