How to use DrawBridge

1. Load your PDF - Drag & drop onto the upload zone, or click Upload & Process PDF to pick a file.
2. Set DPI (optional) - 300 DPI works for most drawings. Raise it for finer detail on dense plans.
3. Process - After selecting a file, the button uploads and processes in one step. Use the page thumbnails to navigate when done.
4. Create layers - Enter a name, choose Point / Line / Polygon, and click + Create Layer. Drawing starts automatically on the new layer.
5. Switch layers - Click any layer row to make it active and start drawing on it (orange halo = active).
6. Digitize - Click to place points. For lines or polygons, click to add vertices and double-click to finish. Backspace removes the last vertex; Cmd/Ctrl+Z undoes the last feature. Hold Spacebar to pan without interrupting your work.
7. Select & Delete - Click ↖ Select, then click any feature to select it (highlighted in yellow). Press Delete or Backspace to remove it.
8. Manage layers - Click ⋯ on any layer to rename or delete it.
9. Export & Download - Choose a format (GDB, Shapefile, GeoJSON, KML) and click Export & Download. The file downloads automatically.
10. Session - Expand the Session panel to save your work and resume it later.
