Combine All Road Surfaces into One
In some situations a user would like the road surfaces (roadsurface, shoulder, ditches) to be joined to one big surface because of requirements in export to 3rd Party solutions.
The road task doesn't hold a surface like this so the user needs to do a triangulation to combine the surfaces to one bigger surface.
This can also be applied for multiple road tasks surfaces that are side-by-side.
Start a Ground Surface task
Pick the road task as input
Specify to only include the road surface features (here you can use the global attribute filter: “Medium = On terrain”
Go to settings in Ground Surface task
Go to TIN priority > Turn OFF “Keep TIN structure”
Go to TIN breaklines > Turn ON “Use TIN edges from surface geometry as breakline”
Close the settings dialog
Use all the same road surfaces used as input to the task also as “Outer boundaries” for the task
Specify a different target feature if it is relevant
Complete the task
Note: Some triangulations can take extended time to complete.
