The first step was to create a body with a simple rectangle sketch, then using the boss-extrude feature to make a rectangular prism.

The second step of designing the body of the car included using the style spine feature to outline a sketch of my car's inspiration, a Ferrari F40, then cutting that sketch out of the rectangular prism with the extruded cut feature. (parameters for the cars design prevented me from designing a basic replica)

The first step to creating the wheel well was to outline circular sketches with a radius of 14mm on the front and back sides of the car, then use the cut extrude feature to cut out the wheel well area with a depth of 10mm.

Next, the axles were inserted into the center of the wheel well cut-outs by sketching circles with a radius of 8mm to fit the fixed bearings provided by the instructor, then made 3-dimensional using the boss-extrude feature out 9mm from the face of the wheel well.

The first example of this is behind the rear tires where the sketch feature was used to outline where a hole would be cut out with the cut extrude feature. This cut went up to the face of the wheel well allowing the air circulating around the tires a smooth escape.

The next step of the rear airflow holes used the three-point arc feature to sketch an arc along the inside of the airflow cutout to help direct the flow of air out the back of the car. 

The second airflow section is a chamber located between the rear and front tires created using a rectangular sketch on a plane made with the reference geometry located in the middle of the car. The airway through the car was cut out with the cut-extrude feature on mid-plane to go through both to the front and the back of the car.

The final step of this airflow hole was using the style spline feature to sketch a curved long along the inside of the cut out rounding out the inside of the chamber directing and increasing the speed of airflow through the chamber.

The first step to making the grill was using the cut extrude feature to cut out an area from the front face of the car back to the wheel well.

Next, the fillet feature was used to soften the edges and help direct airflow throughout the grills. The entrance of the grill and the front face of the car were also filleted to make it smoother and more aerodynamic.

Inside the grill, small cylindrical shapes were extruded between the top and bottom faces of the cut-out area to help break up the airflow through the grill and add some really cool details to the car. The cylinders were replicated with the linear pattern feature before the entire left side of the car, including the wheel wells, fillets, chamfers, grill, and body features, were mirrored over the right plane to the right side of the car.
