The predator drone was made using sweeps, extrudes, revolves, and patterns. The sweep paths were acquired from data points imported from Notepad documents. Dimensions for the airfoil were acquired from an aviation website.

The car wheel assembly is comprised of a wheel, hub cap, and tire. The wheel was created using a revolve of the profile for the outside and a revolve of a spline to create the front surface. Extrude cuts were then created and patterned about the center to create the wheel design. The tire was created by revolving the profile and projecting tread outlines onto the tire to be cut out. The tread cuts were then patterned around the wheel and mirrored across the center. The hub cap was created with a revolve and projection of the text onto the round surface. The text was then thickened to give it volume.

The chain loop was created by using a pattern of a chain link along a 2D reference outline. Points were assigned on the loop which allowed an axis on the link to be constrained to it. A constraint was placed to make the right plane of the link and the assembly be parallel. These constraints were used to pattern the link at each point, completing the loop. The link was created using two sub assemblies. The first sub assembly included a set of link plates, bushings, and rollers. The second sub assembly included another plate and two pins which connect each of the bushing/roller assemblies to each other.

The heat sink is used to simulate a how heat would dissipate from a computer CPU chip. A heat load was applied to the bottom surface. The hottest points are seen to be closes to the source and become cooler the further way they are from the source.

The butterfly valve is made up of a body, arm, shaft, and plate. The arm is able to rotate the shaft to open and close the valve inside of the body. The nuts and screws were sourced for the Solidworks Toolbox.

The Jansen mechanism was assembled by mating the circular edges of each component to the respective edge of the other parts. A motor was set to rotate the mechanism so that all of the parts would move accordingly. A position, velocity, and acceleration analysis was performed at each of the lower ternaries.
