The appearance of the product must fit with the surrounding furniture. Designers often say, “form follows function,” meaning the cabinetry must first serve a purpose. If the product is not functional, even careful styling will not make it useful. 1.1.2 Design Ideas Once the form and function of a product are considered, sketch your ideas. Use your sketches to document your thoughts and to compare alternate designs. Production cabinet shops often create their designs with a computer-aided design (CAD) sys- tem, Figure 1-6. 1.1.3 Design Variables Patrick A. Molzahn Figure 1-6.
