What was done
WoodSketch is an open-source 3D modeler for woodworkers that replicates SketchUp behavior. It is a clean-room implementation and includes an MCP server for AI agent integration. Development commits include Co-Authored-By trailers for Claude Opus 5 and 5.5.
WoodSketch is a 3D modeler designed for woodworking, providing features such as joinery, cut lists, and wood movement checks. The application is a clean-room implementation; the author reports that no SketchUp code, SDK, or artwork was decompiled, disassembled, read, or copied. The .skp file reader was developed by examining file structures independently. The project is written in Rust using the egui and wgpu libraries. The application includes a command-line interface, woodsketch-cli, which functions as an MCP server for Claude and other agents to build drawings from JSON recipes. Several commits in the project repository include Co-Authored-By trailers naming Claude Opus 5 and Claude Opus 5.5. Source code and build instructions are available at while the project website at provides installers for Windows, macOS, and Linux. The software supports OBJ and STL export, autosave, and crash recovery.
