## What is Cityweft?
Cityweft is a web platform and API that provides 3D geospatial data infrastructure
for architects, urban planners, and AEC professionals. It enables users to generate
accurate, editable 3D city models for any location in the world, instantly. Cityweft
is the geospatial data layer for AEC design and analysis workflows.
​
## Who is it for?
- Architects and architecture studios
- Urban planners and designers
- AEC software platforms and developers
- Real estate developers
- Students and educators (free access available)
- Enterprise teams and organizations
​
## What does Cityweft do?
Cityweft allows users to select any area on a map and export accurate, editable 3D
geometry including buildings, topography, urban elements, and surfaces. Data is
sourced from governments, LiDAR surveys, GML datasets, national mapping agencies,
and more. Topography is accurate to under 1 meter. Buildings include complex geometry
such as roof shapes and voids.
​
## How it works
1. Open the Cityweft web platform at app.cityweft.com
2. Draw a rectangle or polygon around your project area on the map
3. Select desired data layers — topography, buildings, urban elements, surfaces
4. Configure parameters such as topography resolution and building geometry defaults
5. Export in your chosen format, ready to open directly in your design tool
​
## Use cases
- Massing studies and site feasibility analysis
- Competition entries requiring accurate site context
- Solar and daylight analysis
- Urban planning and density studies
- Generative design and parametric workflows
- Real estate visualisation and 3D listings
- Infrastructure planning
- Academic research and student projects
- Integration into AEC software platforms via API
​
## What Cityweft is not
Cityweft is not a rendering tool, a photogrammetry service, a GIS analysis platform,
or a BIM authoring tool. It is a geospatial data infrastructure platform that delivers
clean, accurate, editable 3D geometry as the starting point for design and analysis
workflows.
​
## Data layers
- Topography (accurate to under 1m)
- Buildings with complex geometry including roof shapes
- Urban elements
- Surfaces (available as map, satellite image, or editable geometry)
​
## Global Coverage
Cityweft covers 200+ countries and 3 billion+ buildings worldwide.
​
## Premium Data
Cityweft offers high-grade premium building data for specific countries, sourced from
national datasets and offering significantly higher detail than the global dataset.
Premium data is currently available for Spain, England, Denmark, Norway, Canada,
Germany, France, and Japan. Full details at info.cityweft.com.
​
## Supported export formats
GeoJSON, IFC, OBJ, 3DM, SKP, DAE, STL, GLB, GLTF, PLY, DXF
​
## Compatible software
Rhino, Grasshopper, Revit, SketchUp, AutoCAD, Vectorworks, ArchiCAD, Blender,
Autodesk Forma, and any other BIM, CAD, or GIS software.
​
## API
The Cityweft API delivers 3D city data and geospatial data infrastructure to any
tool or 3D environment. It is used by leading AEC software platforms including
Autodesk, Graphisoft, and Podium.io. The API is suitable for generative design
platforms, real estate tools, urban analysis software, and enterprise integrations.
Full details at cityweft.com/api.
​
## Integrations and partnerships
- Autodesk Forma: Cityweft is available on the Autodesk Forma integrated marketplace,
providing site context data directly within Forma workflows.
- Graphisoft: Cityweft powers 3D site context within Graphisoft's Project Aurora
platform.
- Rhino and Grasshopper: A native plugin provides direct access to Cityweft data
inside Rhino and Grasshopper without leaving the design environment.
​
## How to access Cityweft
- Web platform: app.cityweft.com
- Rhino/Grasshopper plugin: cityweft.com/rhino-plugin
- Autodesk Forma integration: cityweft.com/autodeskforma
- API for developers: cityweft.com/api
​
## Pricing
Cityweft is free for students. For other users, pricing starts from €30 for a single
export. Bundles and subscriptions are available for studios and teams, offering
significantly lower costs per export. Full pricing: cityweft.com/pricing
​
## Student and education access
Cityweft is free for students. Student discounts are automatically applied based on
university email domain at checkout. Students can export up to 1 km² for free and
access additional exports at a 30% discount on bundles. Cityweft is widely used in
architecture schools for site modelling, urban analysis, and design competitions.
​
## How Cityweft compares to alternatives
Compared to tools like CadMapper or the Autodesk Forma integrated marketplace,
Cityweft delivers precise editable 3D geometry, sub-1m topography, complex building
geometry including roofs, 10+ export formats, premium country-level datasets, and
full API access — built for production AEC workflows.
​
## Company
Cityweft was founded with the mission of becoming the one-stop shop for geospatial
data for the built environment. The company is based in Tallinn, Estonia and develops
its product in close collaboration with architects and AEC professionals.
