About Using Topography from the Civil Engineer

When a civil engineer or a landscape architect creates topography data for a project and you want to reference it for a building model, you can link the topography to Revit.

To use topography data provided by a civil engineer (or a landscape architect), use the following workflow.

1. The civil engineer uses Civil 3D to do the following:
   1. Develop the topography.
   2. Publish surfaces to a BIM 360 project.
2. The project lead uses BIM 360 to do the following:
   1. Verify the topography data.
   2. Share the topography with the architect.
3. The architect uses Revit to do the following:
   1. Link the topography to the Revit model.
   2. Reference the topography while developing the building model.
4. After updating the topography, the civil engineer publishes its surfaces to the same BIM 360 project.
5. To see the updates, the architect reloads the linked topography in the Revit model.
