dsh-sketchup

When modeling in SketchUp, getting a second opinion on a Ruby snippet, bulk-editing a selection, or reading the current model structure used to mean leaving the app and opening a terminal. dsh-sketchup embeds an authenticated DeepSeek Harness chat window directly inside SketchUp and injects a core-js polyfill before the bundled Chromium UI loads, patching missing standard APIs like Iterators, Set operations, and array copy methods so modern front-end code runs in the restricted built-in browser.\n\nCore capabilities span reading model metadata, active selections, the current edit path, and bounded entity geometry; performing structured operations such as creating boxes or cylinders, selecting or deleting entities, switching active tabs, and saving the model; and enabling Ruby plugin writes and hot-reloads in a specified Plugins subdirectory on demand. Every session is bound to a specific SketchUp instance—if the instance drops, the call errors out rather than silently re-routing to another open model. Geometry coordinates use SketchUp s internal unit (inches) throughout.\n\nBest suited for Windows practitioners running SketchUp 2024 (24.0.484, Ruby 3.2.2) who want AI-assisted modeling without leaving the viewport. Plugin write and load permissions are off by default; enabling them still requires an explicit confirm flag on every action, making it a good fit for security-conscious users who value low-friction AI collaboration. The project is in alpha pre-release status and has not yet been validated on other SketchUp versions.
