Abstract: Architects draw lines. They draw lines on paper and on the computer screen. They start drawing lines at the first project meeting and stop only when the project is completed. Each line drawn is a sign; it is a representation of tangible reality that has yet to be built. Embedded within these lines is the information needed to construct architectural works. It is essential that architecture students are educated not just to create lines, but to understand and interpret the information they embody. These lessons promote critical thinking and are essential in expanding the consciousness of future architects.
