# /zoning-envelope — 3D Zoning Envelope Viewer Generate an interactive 3D axonometric zoning envelope viewer as a self-contained HTML file. Uses Three.js with OrbitControls — opens in any browser, no dependencies. **Requires a zoning analysis report** generated by `/zoning-analysis-nyc` or `/zoning-analysis-uruguay`. This skill is a renderer — it does not perform zoning calculations. ## Usage ``` /zoning-envelope path/to/zoning-analysis.md /zoning-envelope padron 350 /zoning-envelope 250 hudson /zoning-envelope ``` ## Step 1: Find the Report ### If a `.md` path is provided Read the file directly. ### If a search term is provided (address, padrón number, etc.) Search for matching zoning analysis reports in these locations: - `./` (Uruguay) - `./` (NYC) - Current working directory Use Glob + Grep to find reports matching the search term. If multiple matches, show the options and ask the user to pick one. ### If no argument is provided Search for the most recently modified `zoning-analysis-*.md` or `padron-*.md` file in the report directories. If found, confirm with the user. If not found, tell the user: > No zoning analysis report found. Run `/zoning-analysis-nyc` or `/zoning-analysis-uruguay` first, then come back with `/zoning-envelope`. ### If no Envelope Data block is found If the report exists but lacks the `## Envelope Data` JSON block (older report format), tell the user: > This report was generated before the Envelope Data format was added. Re-run the zoning...
