<p class="mb-30">As an avid tea drinker, I enjoy taking moments to recharge throughout the day with hot cups of tea. As a result, when I was assigned to reverse engineer an object consisting of complex curvatures in my advanced CAD class, I knew that I had to model my teapot. In addition to modelling the object within SolidWorks, I also thoroughly documented the design process to describe any challenges that I encountered and the methods I used to overcome them. The 40-page design report documenting the process can be viewed <a href="assets/img/portfolio/Reverse_Engineering_Teapot/David Spielman ME 371 Project 1 Report.pdf"><u> here</u></a>.</p>
<p class="mb-30">Front, side, top, and isometric views of the SolidWorks assembly created for the teapot, with comparisions to images of the actual teapot, are shown below.</p>

<p class="center">Isometric view of the teapot.</p>
<p class="mb-30">Once the assembly was complete, engineering drawing files were made using SolidWorks for both the teapot body and the teapot lid separately (see images below). All units in the drawings are in millimeters, and dimensions for the complex curves are not included. This is because if these parts were to be fabricated, they would likely be manually machined or machined by a computer. Additionally, dimensions for sketches made using the split curve projected on a surface were unable to be made in the SolidWorks drawings. To see these dimensions, refer to Figure 9 and 10 in the <a href="assets/img/portfolio/Reverse_Engineering_Teapot/David Spielman ME 371 Project 1 Report.pdf"><u> design report</u></a>. </p>

<p class="mb-30"> </p>
<img src="assets/img/portfolio/Reverse_Engineering_Teapot/Teapot Lid Complete (10.21.21).JPG" class="img-fluid" alt="nail_dryer_fan_isometric">
<p class="mb-30">The assembly of the teapot turned out well. The measurement methods for most sections of the teapot provided an accurate representation of the real object within SolidWorks. If I had to do this project again, knowing what I now know after completing this project, I would avoid using the sketch picture tool to estimate the curvature of the teapot spout. I encountered many issues with the angle and scale of the images I tried using for reference (as detailed in the modelling section for the teapot spout earlier in the report). Instead, I would employ a similar technique that I used to measure the curvature of the teapot handle. Using a dry erase marker and a ruler to measure vertical and horizontal distances, I would measure various points along the spout and connect them with a sweep to create guide curves for the lofted boss for the spout. This approach may also eliminate the need to create an angled cut since there would be no reference picture, and the measurements for the sweep would terminate along the incline of the angled cut. This would make the modelling of the teapot body more efficient and accurate. </p>
<p class="mb-30">Through this project, I gained confidence using lofts, sweeps, and modelling complex objects in SolidWorks. I also learned more about a some useful features in the software, most notably the split curve function and the lofted cut function. Measuring the teapot components and documenting the entire design process was also a useful creative exercise that helped me to use my problem solving skills to accurately model the teapot. The skills I developed through working on this project will no doubt be helpful to my development as an engineer.</p>
