SolidCraft
SolidCraft: an open-source parametric 3D CAD application
...The software supports assemblies, reusable parameters, and geometric measurements. It runs on Windows, macOS, Linux, and web browsers without requiring proprietary CAD infrastructure. A command-line interface enables scripted modeling, rendering, and file exports. SolidCraft also includes a Model Context Protocol server that allows AI agents to create, inspect, and modify designs through structured commands. Its architecture supports interactive design and automated engineering workflows.
