It would be beneficial to have the ability to specify surface math logic - Above Existing, Below Proposed, and Below "Floodplain" (variable plane) to get good floodplain volumes.

Terrain filters have the ability to use the Feature Definition, but a lot of the time we have elements that we do not want all elements of a feature definition to be captured by the terrain filter. Our current workaround is to have multiple versio...

When editing a Complex Terrain Model, clicking Apply closes the dialog box. The user often wants to make additional edits to the Terrain Model. Allow the dialog box to persist until the user closes it.

When adding extra vertices along linear elements it improves the accuracy of terrains
