On the left, is the dimensioned multiview sketch of our 3D modeled bridge. In Fusion, 1 inch translates to 6 inches in real life. To make sure that the bridge was fully supported and sturdy, we added trusses on the top and sides of our bridge. We also included a beam on each column to make sure the main structure does not bend. To make the bridge, we used sketches, extrusions, lofts, constraints, and dimensions. This made sure that every measurement was precise and equal.
Our 3D print came out okay because the overall shape was how it was modeled in Fusion360. However, the truss members on the top were very thin and fragile because there were many supports that had to be ripped off. The printing hangoff angle also affected how the members printed out.
