How to remove a waterway from the heightmap

This How-to contains the steps on how to create aset of Grid Overlays that calculate a leveled terrain height around waterways. The resulting Grid Overlay can be used to either directly adjust the terrain height of the Current Situation, or applied to the Future Design with a Measure using Grid Spatials

• 
  Original Measure of City Plan with bridge connections situated under water and on sloped terrain.
• 
  Effect of using a Grid Spatials to adjust terrain height and type.

5. In the Grid Spatial's Detail Panel, click on the Add button to select a Grid Overlay to apply.
6. Select the Grid Overlay that represents the leveled terrain. (See this How-to).
7. Uncheck the option Calculate Area from Grids Automatically.
8. Click on the Draw Area button to start drawing a manual selection.
9. With the Brushes panel opened, draw a selection.
10. Click on Apply Selection to finalize the selection
11. Optionally select a Terrain Type to override the existing Terrain. (Advisable in case of Water)
