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 overdimensioned. 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.  \n1. Introduction  \nWhen starting to learn a CAD software, students may focus on the mechanics of using the software (e.g. , clicks of the mouse needed to create a line or a circle) but they may not be fostering an understanding of the number and types of dimensions needed to define the shapes they are generating and how these dimensions are affected by their choice of constraints. Eventually, students will be required to create engineering drawings of the 3D models following the standards of ASME [1-2], or the like, and any additional rules set by their instructors. When creating an engineering drawing, it is imperative that only the necessary dimensional data be provided. Providing more dimensional data than necessary or omitting data will cause confusion when manufacturing the component. Figure 1 illustrates the differences between the dimensions and constraints in a sketch representing the cross-section of a 3D model and an example of how the same cross-section might be dimensioned in an engineering drawing.  \nSketches are fundamental to mechanical component design because they can be mapped to the manufacturing operations used to fabricate the components. In this work, a sketch is a 2D, planar geometric model comprised of [3-6]:  \n• 2D curves such as line segments, circles, and circular arcs;  \n• references to locate the curves on the sketch plane (e.g. , coordinate axes);  \n• dimensional constraints (or simply dimensions) to specify the size, location, and orientation of the curves;  \n(a) (b)  \n(c)  \nFigure 1.
