Is there a way to create a TIN or DTM from a proposed 3D design file?

Question

I have completed my design in SS3 OpenRoads, and I currently have a default model and a 3D model for my design. I would like to create a TIN or DTM of the entire 3D model because it has all the proposed surfaces and elements I will need. Is there a way for me to create a TIN of the entire 3D model or will I have to create a TIN of each terrain model? This also poses a problem because I have only seen tools to create a TIN or DTM from terrain- are there options to include linear templates in the proposed TIN?

If you have multiple Terrain Models that you wish to combine before creating the TIN file, run the Create Complex Terrain Model command to combine them. It has options to merge and/or append terrains together.

The easiest way to create a terrain from all your corridors/linear templates at once would be to make sure your Top Mesh Feature Definition is the same for the Design Stages that you have assigned to the corridors/linear templates, then run the Create Terrain Model by Graphical Filter and import all the meshes into one Terrain.
