Assignment: Select an oddly shaped object. Make one drawing of the object as you see it. Then, imagine how you would slice it into 2d pieces in order to recreate it, and draw samples of these slices.
Here is my wonky 3D rendering of a toy truck:
Here are the 2D slices. I split up the truck into four different sections–the wheel and axle, the front, the rear, and the staircase divider between the front and the wheel. If I’m correct, I could make a truck out of 18 pieces. This 18-piece count does not include the wheel and axel parts, or whatever I’d need to connect the wheels and axel to the body of the truck.
