Topoplan
Digital terrain modelling and documentation tools that make surveyors’ work more efficient.
Overview
Terrain Models
for Surveyors
for Surveyors
The Topoplan module extends the nanoCAD Platform with tools for digital terrain modelling and documentation. It is designed to make the work of surveyors more efficient.
Build surfaces from points, point clouds and elevation grids, construct contours and profiles, and calculate volumes for excavation works.

Key Features
From Survey Points
to Finished Plans
to Finished Plans
Advanced Surface Creation
Create TINs by points, explode clouds into points, import elevation grids, and convert models to 3D faces, submeshes and polyface meshes.
Civil 3D Object Support
Objects made in Civil 3D are displayed instead of showing as proxy graphics; the Properties panel edits their properties and display style.
Textures on Meshes
Flat texture overlay from point clouds, raster texture mapping, and mesh colouring by height.
Volume Calculations
Calculate volumes between models: total, difference and balanced volumes for excavation works.
Multiple Data Sources
Build terrain models from text-file points, DEM imports, and points unloaded from point clouds.
Surface & Contour Tools
Flip and delete edges, edit vertexes, add structure lines and remove faces with edges of a certain length through mesh boundaries.
Digital Terrain Models
Build Surfaces
From Any Survey Data
From Any Survey Data
Create digital terrain models from multiple data sources and then refine the surface.
- Import points from text files (XYZ, TXT) and import DEM data
- Unload points from previously imported point clouds
- Create TINs by points or import elevation grids
- Add structure lines, move vertexes and flip or delete edges
Relief & Contours
Contours, Profiles
and Volumes
and Volumes
Tools for working with relief elements and finishing terrain documentation.
- Construct and remove contour lines, with bergstriches (hatching) and labels
- Build profile lines and generate 3D polylines on meshes
- Calculate total, difference and balanced volumes for excavation works
- Colour surfaces by elevation or apply raster textures

Questions
Points from XYZ/TXT text files, DEM imports, elevation grids and points unloaded from point clouds.
Yes. It calculates volumes between models — total, difference and balanced volumes for excavation works.
Yes. It imports and exports surfaces in LandXML, and imports and exports polyline and point objects in *.SHP and *.MIF formats. nanoCAD 26 adds KML/KMZ import.
Topoplan displays objects made in Civil 3D instead of showing them as proxy graphics, and lets you edit their properties and display style in the Properties panel.
