SolidCraft

SolidCraft is an open-source parametric 3D computer-aided design application built entirely in Rust for mechanical modeling and engineering workflows. It allows users to create constrained sketches and transform them into editable solid models through operations such as extrusion, filleting, and shelling. A parametric feature timeline preserves modeling history and automatically rebuilds geometry when dimensions change. 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.
