The Align terrain to shapes tool aligns terrains to selected shapes.
To align terrain to shapes, click the Align terrain to shapes tool or click Terrains > Align terrain to shapes in the main menu.
The Align terrain to shapes tool aligns one or all terrains to the shapes currently selected.
The Align terrain to shapes tool has the following options:
The terrain that should be aligned or All.
If enabled, terrain vertices below selected shapes are aligned.
Maximal raise distance
If the distance between the terrain and shape is smaller, terrain vertices below the shape are raised.
If enabled, terrain vertices above selected shapes are aligned.
Maximal lower distance
If the distance between the terrain and shape is smaller, terrain vertices above the shape are lowered.
If enabled, a small border region around the shapes is aligned, too.
Write cut/fill volumes to attributes
If enabled, for each selected shape cut and fill volumes in cubic meters are approximately calculated. The values are written into the object attributes (fields cutVolume and fillVolume).
Applies a smooth transition method at the border between the edited and the original terrain.
|Border range (m)|
|Border gradient (°)|
Elevation delta maps
When aligning terrains, the original heightmap of the terrain is not modified. The elevation data is stored as a separate image file in a subfolder (named after the CityEngine scene) in the project's data folder. These files and folders should not be renamed or deleted. If required, however, you can modify the elevation delta image file with an image processing tool (for example, apply blurring) and store it under the same name.
Use the Align terrain to shapes tool in conjunction with the interactive editing tools.
