Teaching Free-Hand Drawing In Aerospace Engineering
Computer-aided-design classes have largely replaced those dealing with engineering drafting, resulting in an often heard criticism by today’s faculty that engineering students are no longer able to express themselves using simple free- hand drawings (sketches). While engineering students are expected to become proficient with modeling packages, they are seldom asked to think visually and communicate visual ideas with art-based freehand drawing. With the right instructor and short weekly exercises, however, the ability to sketch in engineering classes need not be lost. Likewise, free-hand drawing techniques can help students to develop and refine their visualization skills.
In an undergraduate aerospace engineering design class, the professor advocates the use of an art-based approach to help students think at deeper and more creative levels. By his modeling the drawing of airplanes throughout the semester, he talks through essential design components and tries to get the students to focus on seeing and visualizing. In this paper, we will describe the instructional processes he uses, the reasoning behind his approach, student drawing examples (to illustrate abilities at the beginning and end of the semester), student feedback on the drawing process and their perceptions on how it influences their learning, and suggestions on how to implement free-hand drawing techniques into your classes.
Many faculty voice concerns that students are no longer able to sketch or effectively convey their ideas graphically. In aerospace engineering, students’ depictions of aircraft and spacecraft lack detail and sophistication, revealing sketching skills at elementary levels. Yet competent engineers need to be equipped with proficient basic drawing and visualization skills.
As an engineering professor, it was painfully obvious to me that students lacked free hand drawing skills and that these skills are needed for improving their visualization and spatial orientation. Approximately ten years ago, I was tired of hearing “we can’t do this” from my students, and I figured the primary reason that they lacked these skills was simply that no one had ever shown them basic drawing procedures. Since then, I have attempted to do this and have seen dramatic results that followed when sketching is taught just fifteen minutes or so weekly during the course of a semester. Initially, the goal of this effort was simply to provide students with a skill to help them understand their ideas and present them to others.
After years of intuitively teaching free hand drawing skills, I began to explore this issue further. Some research shows that creativity is almost entirely a right-
