The Sectioning tool allows you to generate an elevation profile along a line you draw over your 3D data. This is useful for analysing terrain changes, identifying slopes, or reviewing elevation differences across specific paths.
How to Generate an Elevation Profile
1. Draw a Line
Navigate to the Draw Tool and trace the path where you want to generate an elevation profile.
2. Enter Annotation Details
Provide the necessary information under the Details tab, then switch to the Measurement tab to access the Sectioning feature.
3. Set Measurement Reference
Choose the layer you want to analyse. Ensure you select a supported layer type.
Note: Supported layer types include 3D Meshes, IFCs, and OBJs (excluding terrain).
4. View the Profile
Once your line is drawn and the measurement reference set, the tool displays an elevation profile graph showing elevation (y-axis) against distance along the line (x-axis). The points along the section are sampled approximately every 6 cm.
5. Export Data
Click Export to CSV to download the elevation profile data for further analysis or reporting. Exported data will be in cartographic coordinates - longitude, latitude, and elevation.
Pro tip: Here’s a sample CSV file you can download.
Understanding the Graph
X-Axis: Represents the distance along the section line (in metres or feet).
Y-Axis: Shows elevation values along the section path.
Elevation fluctuations indicate rises and falls in terrain or surface features.
Changing Units
You can switch between Metric, Imperial, or US Imperial units anytime to match your preference or project requirements.
