National Exams, 04-BS-15 Engineering Graphics & Design Process, 2016-Dec. Closed-book, no calculator; three multi-part questions constitute a complete exam paper, and all sketches must be freehand (no straightedges).

Reference texts: Bertoline & Wiebe, Technical Graphics Communication — multiview, section and auxiliary views, isometric pictorials, feature-based solid modelling; Giesecke et al., Technical Drawing with Engineering Graphics — ASME Y14.5 / CSA B78.2 dimensioning and geometric dimensioning & tolerancing (GD&T).

How the figures below were made: none of the exam figures carries numbers, so every view in this solution is scaled from the printed figure (proportions measured from the printed figure of the paper). The millimetre values in the notes are those scaled proportions, used only so the views line up; on the exam you would sketch the same proportions freehand.
