Building 3D wheel models has its own unique challenges and requires other skills to building a car body. Accuracy is paramount, which means using the snap function to ensure points and angles are always correctly positioned. Tyres with rubber tread are even more complicated and the slightest error will make it impossible to create a closed model that can be printed or used for prototyping. As such it was important to understand how to do this and so I produced a few variations on wheels and tyres to learn how.
