When the terrain height brush is used in live sculpting mode, modifications to the elevation model are visualized as you draw them, where you draw them. Applying the modifications to the elevation data is a separate, confirming step.

Editor → Current Situation (Ribbon tab) → Terrain (Ribbon bar) → Edit elevation model (Dropdown)
How to modify the elevation model in live sculpting mode:
  1. Set the terrain height brush to "Live sculpting" style.
  2. Set the brush type (next to "selection") to only RAISE, LOWER, or FLATTEN as desired.
  3. Without clicking, move the cursor in the 3D Visualization in the location where terrain height should be adjusted.
  4. Take note of the "Height at cursor" for some insight into appropriate height values.
  5. Set the desired height as desired.
  6. Set the desired angle as desired.
  7. Click (and drag) in the 3D Visualization to draw a modification.
  8. If desired, adjust the height and angle settings and create additional modifications.
  9. When all desired modifications have been created and are deemed appropriate, select "Apply Changes"
  10. The project's elevation model will now be modified with the modifications you have made.


  • When using RAISE, terrain is only raised to the desired level. Terrain higher than the desired level is not lowered.
  • When using LOWER, terrain is only lowered to the desired level. Terrain lower than the desired level is not raised.
  • When using FLATTEN, terrain is adjusted to the desired level, regardless of whether that requires the terrain to be raised or lowered.
  • Dragging while clicking to adjust a line of terrain (rather than just a single point), is effectively treated as a sequence of points rather than a continuous line.
