For the final project in ME 190, SDSU’s computer-aided design course, I worked with two classmates to model a machinist’s surface gauge in SolidWorks and produce a full set of working drawings. The assembly has 11 components, including a cold-rolled steel base, a rocker arm, a scriber rod (the pean), adjustment screws, and compression springs. We split the parts across the team and combined them into a single assembly. I modeled and drew the Base, Rocker, and Conical Spacer. I also made the final assembly drawing, which shows an exploded isometric view with assembly lines, balloon callouts, and a bill of materials. Each part sheet follows ANSI dimensioning standards. Mating features such as the pivot bores carry tight tolerances, for example +0.005/−0.000 in, so the parts fit together as designed.
