  Sketch2Prototype is an AI-based framework that transforms a hand-drawn sketch
into a diverse set of 2D images and 3D prototypes through sketch-to-text,
text-to-image, and image-to-3D stages. This framework, shown across various
sketches, rapidly generates text, image, and 3D modalities for enhanced
early-stage design exploration. We show that using text as an intermediate
modality outperforms direct sketch-to-3D baselines for generating diverse and
manufacturable 3D models. We find limitations in current image-to-3D
techniques, while noting the value of the text modality for user-feedback and
iterative design augmentation.
