SketchGraphs: A Large-Scale Dataset for Relational Geometry in CAD Central Question: What is SketchGraphs and why does it matter for CAD and machine learning research? SketchGraphs is a dataset of 15 million CAD sketches extracted from real-world models. Each sketch is represented as a geometric constraint graph, where nodes are geometric primitives and edges represent designer-imposed constraints such as parallelism, tangency, or perpendicularity. The dataset is designed to support machine learning for design automation and geometric program induction, and it provides both raw and processed data formats for different use cases.

GenCAD: AI Technology for Generating Editable 3D CAD Models from Images 1. Background and Challenges In industries like automotive manufacturing, architectural design, and medical device development, 3D CAD models serve as the critical bridge between creative concepts and physical production. Traditional CAD workflows face two persistent challenges: High Operational Complexity: Requires specialized expertise to execute parametric commands for modeling Slow Design Iteration: Manual refinement cycles between conceptual sketches and manufacturable models Existing AI generation technologies primarily focus on unstructured 3D representations like meshes, voxels, or point clouds. These formats lack the engineering precision needed for direct manufacturing. GenCAD addresses this …
