How to Get 3D Site Models from Maps (GLB OBJ STL 3DM)

3D site models from maps turn a latitude-longitude pin into massing context you can orbit, section, and render without modeling every neighbor by hand. The key is choosing the right mesh format: GLB for quick imports, OBJ for universal exchange, STL for simplified solids, and 3DM for Rhino-native editing.

UrbanEyes Site Maps ships the full 3D set on paid exports: GLB, glTF, OBJ, STL, PLY, 3DM, and SketchUp DAE - alongside 2D CAD and SVG from the same ring.

What a 3D site model should contain

A useful 3D site model for architecture includes:

• Extruded or mesh buildings around your plot
• Terrain when the site is not flat
• Optional roads, water, and green layers for readable context
• Correct georeferenced scale (verify on import)

It is design context, not a BIM model with doors and MEP. Expect to simplify for performance.

Format guide: GLB, OBJ, STL, 3DM

Format	Best for	Notes
GLB	Fast preview, web, many importers	Compact binary glTF
glTF	Realtime pipelines	Often paired with GLB
OBJ	Blender, generic mesh tools	Widely supported
STL	3D print experiments, simple solids	No color/material rich
PLY	Point-cloud-style experiments	Check mesh vs points
3DM	Rhino-native workflows	Best Rhino fidelity
SketchUp DAE	SketchUp import	Full paid pack

UrbanEyes includes all of these in the full paid export zip, not as separate purchases.

Step-by-step: 3D site model from UrbanEyes

1. Open UrbanEyes Site Maps
2. Pin your site anywhere worldwide
3. Set context ring (free up to 1 km; larger on paid)
4. Enable buildings, topography, trees/parks, roads as needed
5. Export - GLB available on free ring for quick tests; full 3D pack on paid
6. Import into Rhino, Blender, SketchUp, or Twinmotion-compatible tools
7. Group as CONTEXT and begin proposal massing

Import tips by software

Rhino:

• Prefer 3DM, fallback OBJ or GLB
• Mesh context is enough for most massing; do not over-convert to NURBS
• Use topography mesh for section cuts early

Blender:

• OBJ or GLB import cleanly
• Decimate modifiers if the ring is large and viewport slows

SketchUp:

• Use SketchUp DAE from paid export; GLB for early tests

AutoCAD:

• Use DXF/DWG for plan context; pair with 3D mesh from OBJ if needed in hybrid workflows

Free ring vs paid 3D exports

UrbanEyes free ring (up to 1 km) includes GLB and other core formats so students and solo architects can validate 3D quality before paying.

Paid rings and subscription tokens unlock OBJ, STL, PLY, glTF, 3DM, SketchUp DAE together with SVG, GeoJSON, KMZ, and CAD - one zip, one checkout.

Pricing: PAYG roughly €18 to €110; subscriptions €20/10, €30/20, €80/40 tokens on Basic/Pro/Pro+.

Performance and cleanup

Large urban rings produce heavy meshes. Plan 30 to 60 minutes to:

• Delete distant blocks outside camera view
• Simplify tree geometry if every crown is high-poly
• Confirm units and ground plane at Z=0 convention your office uses
• Replace proxy neighbors with blocks if render farm struggles

Still faster than modeling context from scratch.

When competitors beat standard 3D context

CityWeft delivers premium LoD2 building detail and Revit-native workflows in select markets. When roof complexity and BIM fidelity matter more than mesh interchange, evaluate CityWeft for that coordinate - UrbanEyes remains faster for global schematic 3D.

TopoExport offers strong terrain and vector 3D (OBJ, STL, IFC). Compare terrain mesh quality on sloped large sites if that is the bottleneck.

UrbanEyes optimizes for one export with GLB through 3DM plus CAD and SVG, which fits mixed Rhino/SketchUp/CAD studios.

From 3D context to analysis

3D maps answer "what is there." UrbanEyes Deep Analysis adds metrics, feasibility framing, and environmental modules on the same site when the deliverable grows beyond massing renders.

Use cases that need 3D site models

• Competition aerial and eye-level renders
• Shadow and envelope studies with neighbor massing
• VR/client walkthrough blocking
• Solar orientation tests with real context
• Campus masterplans with topo + buildings

Enable topography whenever any of these apply.

Export your 3D site model

Open UrbanEyes Site Maps, test GLB on the free ring, then unlock OBJ, STL, 3DM, and the full pack for final submissions.

FAQ

How do I get a 3D site model from maps?

Use UrbanEyes Site Maps to export GLB, OBJ, STL, 3DM, or other 3D formats from a site ring, then import into Rhino, Blender, or SketchUp on locked context layers.

Which 3D format is best for Rhino?

3DM is best for Rhino-native workflows. OBJ and GLB are strong alternates for quick imports.

Is GLB export free on UrbanEyes?

Yes. The free ring (up to 1 km) includes GLB among core formats for testing 3D imports before a paid export.

What is included in paid 3D site model exports?

GLB, glTF, OBJ, STL, PLY, 3DM, SketchUp DAE, plus PNG, SVG, GeoJSON, KMZ, DXF, and DWG in one zip.

UrbanEyes vs CityWeft for 3D site models?

UrbanEyes provides broad mesh and CAD formats globally with a free ring. CityWeft can win on premium LoD2 and Revit detail in covered cities when BIM depth is the priority.

Do 3D site models replace BIM coordination models?

No. They are contextual massing meshes for design and visualization. BIM production models still require your office standards and discipline-specific authoring.
