Can I export the terrain as a 3D model?
Yes. Terrain can be included in the 3D model export as 3DM, OBJ or GLB.

Generate terrain with the architectural context around it
Choose a site, enable Terrain and build a 3D ground surface from regional elevation data. Keep the terrain alone or combine it with buildings, roads, water, green areas and trees, then export 3DM, OBJ or GLB.
Terrain meshRhino 3DM · OBJ · GLBContext layers optional
Terrain controls
Useful for design, clear about its limits
Regional elevation source
Terrain is generated from elevation data for the selected area rather than inferred from an AI image.
Visual exaggeration
The 3D workspace lets you adjust terrain exaggeration while evaluating the model.
Not survey accuracy
Use the terrain for architectural context, massing and presentation — not for grading, engineering or construction set-out.
Workflow
From site selection to terrain export
Choose the site
Search the location and draw the model area.
Enable Terrain
Turn terrain on and optionally add buildings, roads, landscape and water.
Export
Download the combined model as Rhino 3DM, OBJ or GLB.
Pair it with analysis
Terrain is more useful when it explains the project
Topography diagram
Generate 2D topography analysis from the Site Analysis workflow.
Slope and drainage
Use the dedicated slope/drainage analysis as a diagrammatic reading of the site.
3D context
Use the terrain mesh underneath the surrounding city model for massing and presentation.
Frequently asked questions
What to know before you export
Can I export contour lines as part of the 3D file?
The 3D file exporter exports the terrain mesh. Contour interval controls are used in the 3D workspace, while dedicated topography diagrams are available separately in Site Analysis.
Is the terrain survey-grade?
No. It uses regional elevation data and is intended for architectural context and presentation, not engineering accuracy.
Can I include buildings with the terrain?
Yes. Buildings, roads and paths, water, green areas and trees can be included alongside the terrain.
What is the maximum export area?
The current 3D file exporter supports selections up to 4 km².
