Engineering Design Graphics
Two-Dimensional (2D) computer-based sketches are fundamental to generate 3D models in many of the Computer-Aided Design (CAD) software applications implemented in engineering graphics and design courses. Furthermore, engineering drawings rely on these 3D models to document and communicate designs. Although much of the dimensional data included in engineering drawings comes from the model’s sketches, students sometimes struggle forming a connection between these resulting in drawings that are either under-dimensioned or over-dimensioned. In this evidence-based practice paper, an instructional method to teach the interaction between sketch curves, constraints, and dimensions is presented with the goal of creating engineering drawings with suitable dimensional data. Exercises that have been developed and refined are presented to illustrate the method and convey best-practice approaches in the classroom. Examples of student work is presented to illustrate the common mistakes made. The method presented is independent of the CAD software and can be taught in first-year graphics courses or even upper-level design courses.
