Recent advances in 2D generative AI are beginning to find applications in highly specialized fields, such as car exterior design. However, the current 2D-centric approach has several limitations: each viewpoint requires a new sketch; maintaining consistency across different viewpoints is challenging; steering design development in the desired direction can be difficult. To address these limitations, we propose a novel design workflow that integrates 3D sketching with 2D generative AI for car exterior design. This workflow enables car designers to seamlessly transition between expressive 3D sketching, detailed 2D drawing, and realistic 2D generation, facilitating view-consistent and progressive design development. We conducted an in-depth user test with a professional car designer, who used our system to produce car exterior concepts for all major body types, demonstrating its potential usefulness during the early stages of car design.
