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.

Process:

1. Start a Ground Surface task

2. Pick the road task as input

3. Specify to only include the road surface features (here you can use the global attribute filter: “Medium = On terrain”

4. 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

5. Use all the same road surfaces used as input to the task also as “Outer boundaries” for the task

6. Specify a different target feature if it is relevant

7. Complete the task

Note:  Some triangulations can take extended time to complete.
