# Use the Terrain / Cross-sections

Many civil engineering related works need to review longitudinal and cross-sections using existing infrastructure and terrain.

In Civillo, a cross‐section is a plane that cuts vertically through the map to reveal a two-dimensional grid of the assets that intersect with the vertical plane.

Using cross-sections in Civillo is easy, add / remove cross-section markers, toggle on or off the hit-line, relative heights, label features, or change the default terrain.

# Cross-section markers

Click on the terrain icon to activate the cross-section panel.

The panel will be activated from the bottom of the web page. Two markers are displayed on the map, with the labels A and B.

Additional markers can be added to the cross-section by left-clicking on the map.

Markers can be removed by right-clicking on the marker label (or next to the marker when in 3D mode).

# Hit-line

The Civillo hit-line labels all elements that the hover line intersects with, each label contains the element sub-layer and the elements reduced level height (RL).

# Relative-Heights

Adjust the hit-line height to indicate the relative fall or gain from the loaded default terrain.

# Auto-Labels
