You can use Terrain Editing to remove a bridge or structure on site. For example, if you have a bridge that’s under construction, you can remove it from your model to measure the earthwork underneath. 

To make a terrain edit, click closely along the boundary of the bridge. The more vertices you add, the more points we have to create the new accurate surface from. 

What if I need to remove something sitting on uneven ground, like a slope? 

If you are removing a structure, for example a bridge head, sitting on a slope you can add breaklines to reflect major topography. 

You can add as many breaklines as necessary to capture the detail of the shape for more complex features.

To make edits to the terrain above or below the existing surveyed surface, click on any vertex of the Terrain Edit and adjust the elevation. To lower or raise the level of the entire Terrain Edit, adjust multiple vertices to reach the desired levels.
