Road network surface

[nikoue]

I have make a road network. Then i make a corridor surface using corridor extends as outside boundary. I also create a boundary in the interior side of the roads with interactively tool, and i use it as a hide boundary. The corridor surface look fine but when i am trying to make a finish Ground Surface pasting the corridor surface after Existing Ground surface then the hide boundary of corridor surface make holes in finish Ground surface. What can i do?

Paste the EGL to a new surface and add the hide boundary from the corridor surface an outer non destructive boundary and then paste this surface into the composite.

The ease of achieving this will also depend on the complexity of the hide boundary as I've assumed the simplest case here. If there are many "islands" you could also draw a rectangle around the full EGL (after pasting to new surface) and add as a hide boundary and then add the "islands" as Show boundaries and finally paste to composite surface.

There are probably other ways to achieve what you are after......

Thanks a lot for your answer.

maybe someone knows something more automatic?

Another option would be to make two separate FG surfaces from the corridor.  One would be for the left side and the other for the right.  Use the interactive boundary tools to define the surface boundaries.  You could then paste these into the copy of EG, without it hiding the internal area.
