The article by Michael Graves that appeared in the New York Times on September 1, 2012 created quite a furor, demonstrating how important this issue is  in the minds of architects. The discussion in the architecture press subsided far too quickly. The role of drawing in architecture that he articulates and the consequences of its fading from practice should be a constant topic of conversation among architects. Take the time to read (or re-read) the article.

In this interview, Daniel Libeskind talks about the essential place of drawing in his practice and in architecture.
