Sketching has always been an essential part of the architect’s creative process. Case in point, architect I.M. Pei drafted his preliminary design for the East Wing of the National Gallery of Art on a cocktail napkin.
Modern architectural sketches combine design intent with data and constraints. The sketch grows in resolution as layers of information are added by different stakeholders. Architects today use both tactile and digital tools for sketching. The conundrum has been to choose either the flexibility offered by freeform modelers or the data-richness offered by BIM tools.
