The car design process involves several steps, starting with drawing and rendering. Designers consider current fashion trends and the popularity of electric and hybrid vehicles. The process then moves on to concept development, clay modeling, digital modeling, and engineering. Physical models are made of clay and fine-tuned before the final design is approved. The design is then prototyped and tested before going into production. Car design software such as Blender, Autodesk Alias, and Siemens NX are used to create 2D and 3D models. To design your own car, you can start by sketching your ideas on paper and then using car design software to create a 3D model. You can also consider enrolling in a car design course to learn more about the design process and techniques used by professional car designers.
