01
Download your CSV
Click ↓ Download CSV above. The file contains X, Y, Z point data in metres, with a UTM origin coordinate in the filename for georeferencing.
02
Open the Massing & Site tab
In Revit, go to the Massing & Site tab in the ribbon. Make sure you are in a 3D view or a site plan view.
03
Create Toposolid from Import
Click Toposolid → Create from Import → Select Import Instance. In the dialogue, choose Specify Points File and navigate to your downloaded CSV.
04
Set units to Metres
When prompted for units, select Meter. All coordinates in the CSV are in metres relative to the UTM origin shown in the download filename.
05
Terrain created ✓
Revit builds the Toposolid surface from your point cloud. Accuracy depends on your plan — up to 0.4m vertical resolution on Pro with LiDAR data.
💡 Keep point count under 20,000 for best Revit performance. Use 6m or 12m spacing for sites over 1km².

Why our data is better

Survey-grade terrain you can import, inspect,

and edit inside your own modelling software.
Most online terrain tools give you a visual, not a buildable model. Topo-grapher is built for the other case. Every output is a clean, editable point set at real-world coordinates, accurate to the resolution of the underlying official survey for your region.
01
Sourced from national mapping authorities
We work with the top-tier LiDAR and photogrammetry datasets published by national mapping agencies and geospatial institutes across Europe, the UK, and North America. The same data your surveyors and planners already reference, made accessible inside the tools you already use.
02
Resolution that actually serves BIM
On Pro, vertical accuracy reaches 0.4m or better in supported regions. That is close enough to drive drainage gradients, tie into site levels, and coordinate with civil engineers without needing to redo the terrain at tender stage.
03
Editable, not baked
The CSV is plain XYZ point data. You import it as a Toposolid, mesh, or NURBS surface and you own it from there. Smooth a point, raise a ridge, trim to a site boundary, the data is yours to shape. No black-box texture maps, no locked formats.
04
Georeferenced, not floating
Every export ships with a UTM origin in the filename. Your model lands at its real-world location, aligned with aerial imagery, cadastral maps, and any other georeferenced layer in your coordination workflow. No guessing, no manual offsets.
05
Consistent across borders
Every region uses a different authority, a different API, a different coordinate system. We handle that so you get a uniform XYZ file whether you are working a site in Copenhagen, the Cotswolds, or California. One workflow, whatever country the project is in.
06
Verifiable against public records
Because the underlying data is from official public sources, every point can be cross-checked against the same datasets used by municipal planners and engineers. If a point looks wrong, you can confirm it against the authoritative record. That matters when you are handing a model to a contractor.
The short version
Other platforms give you a picture of the terrain. We give you the terrain itself, as data, at the resolution your consultants actually need, ready to drop into Revit, Rhino, ArchiCAD, or SketchUp and carry through the whole project.
