Urban Tools
ParametrStudio
Major update - a rebuilt workflow in one click.
• Find, Download & Generate in one step, running in the background; local .osm import and an offline demo.
• Fast and reliable downloads: Automatic uses the Postpass service by Geofabrik with Overpass as fallback, automatic retries, optional custom server.
• Every import is a named dataset with Buildings and Roads; Reload applies new height defaults without downloading again.
• More accurate heights including roofs, courtyards, and feet values.
• Roads as flat Geometry Nodes ribbons with a width per road type, clipped to the downloaded area.
• Five analysis modes with instant viewport preview; Apply Colors creates materials only when you need them.
• SVG plan diagrams that follow the current state of your scene.
• Data stored next to your .blend file with relative paths; Open Folder button.
• One version for Blender 4.2 LTS - 5.2.
Automatic Overpass server fallback. When the main OSM server is overloaded or blocks the request (errors 406, 429, 504), the add-on retries and switches to a European backup server on its own. You can also pick the server manually in the panel. Longer timeouts for slow responses.
Compatibility & stability update - one version for Blender 4.2 LTS - 5.1.
• Fixed the „osm_download.osm not found“ error and downloads that silently did nothing. The cause: with an unsaved .blend, the add-on saved data to one folder and looked for it in another. All data now lives next to your .blend file - just save it before you start; the add-on will remind you if you forget.
• Clear messages instead of Python tracebacks - if you skip a step, it tells you exactly what to run first (e.g. „run 'Download OSM' first“).
• Rewritten networking for reliable downloads across all supported Blender versions; respects the „Allow Online Access“ preference.
• Existing project files from 1.0.4 keep working - no re-download needed.
A fundamental geometry-generation change - from minutes to seconds.
• Buildings are no longer extruded one by one via edit-mode operators (which forced a full scene update per building) - geometry is now built directly in memory with BMesh and written to the mesh in a single step.
Initial release.
- Download OpenStreetMap data by address and radius, directly in Blender
- Extract OSM tags into a JSON file for further processing
- Generate 3D building masses from height and level tags, with OSM metadata in Custom Properties
- Generate 2D road outlines
- Analysis modes: building function, height (random colors), height (single-hue gradient)
- Viewport color preview and material generation for Cycles and Eevee
Sample data: two real locations as .osm files for testing without internet. Import them in the Urban tab via Local .osm. Data © OpenStreetMap contributors, ODbL 1.0.
