AdamsInternational Conference on Learning Representations (ICLR) 2022PaperVideoCode & model weights Vitruvion is a transformer-based model trained to generate parametric computer-aided design (CAD) sketches. It shows promise to augment mechanical design via tasks such as converting hand drawings to CAD models, autocompleting sketches, and inferring intended constraints. Overview Parametric CAD tools are the predominant way engineers specify physical structures, from bicycle pedals to airplanes to printed circuit boards. They empower users to explore parameterized variations on their designs, while also providing a structured representation for simulation and manufacturing. At an operational level, parametric CAD starts with the specification of two-dimensional geometric representations, referred to as “sketches”. A sketch consists of a collection … Read More
