This paper is presentation of resulting physical models that were used to explore the relationship between design modelling in CAD and digital fabrication with plywood sheets. We explored a process in making tabletop models with digital fabrication machines and thin plywood sheets. Each was built from combination of predetermined wood joining techniques and structures. These models are believed work as simulation of full scale constructs that inform CAD modelling. Results illustrate the limited potential of parametric modelling and inform fabrication and assembly of design variations.
