Engineers communicate multimodally using written and visual communication, but there is not much theorizing on why they do so and how. This essay, therefore, examines why engineers communicate multimodally, what, in the context of representing engineering realities, are the strengths and weaknesses of written and visual communication, and how, based on an understanding of these strengths and weaknesses, one can consider using the strengths of each form of communication to address weaknesses in the other. Doing so can possibly enable one to demonstrate for engineering majors how they can, with greater effectiveness, communicate multimodally for representing well engineering realities.
