You can use the Align streets to terrain tool to align graph networks to a terrain (map layers with the elevation attribute defined) or to the y=0 level. You can access the tool in the following ways:
- Click the Align streets to terrain tool on the main toolbar.
- Click Graph > Align streets to terrain in the main menu.
The following parameters control the alignment:
The alignment function to apply to the nodes of the graph.
The terrain to align the graph. All map layers with an elevation attribute plus the y=0 level are listed here.
The offset to add after alignment to the y-coordinate of the nodes.
