Show HN: AI CAD Harness

Adam, a startup co-founded by Zach, has launched an AI-powered CAD harness that integrates directly into Onshape and Autodesk Fusion. The tool helps engineers edit and manage CAD feature trees with features like merging redundant elements, renaming features, and applying fillets. It leverages CAD as code using Onshape's FeatureScript and Python, and utilizes advanced AI models like GPT 5.5 and Opus 4.7 for spatial reasoning.
