Terrain from Scratch
Create a flat or shaped starting terrain, then refine it with terrain tools.
Terrain from ScratchCreate terrain builds an initial ground surface from dimensions, a base elevation and a simple shape. It provides a starting model when you do not have imported terrain. It does not create measured site data.
Open creation
In the Terrain workspace, open Data and choose terrain creation from scratch. Enter Width, Depth and Base elevation. Unit fields follow the project settings; explicit measurements such as 20 m or 60 ft can be entered.
Choose the shape
Under Terrain shape, choose Flat, Directional slope, Bowl or Mound. Non-flat choices expose the applicable elevation-change controls. For a Directional slope surface, Slope direction (downhill) describes the direction in which the surface descends.
Create or replace
Choose Create Terrain, or Replace Terrain when terrain already exists. Read and confirm the replacement warning. Replacement discards the old scratch surface shape and its custom surface data; it does not merge new terrain into the old base.
Inspect and refine
The terrain is positioned using the existing scene, or the project canvas center when empty. Check alignment, dimensions and elevation. Refine the result with Volume Points, Spray Sculpt or grading objects, and inspect contours through Display.
Undo a replacement
Use Undo to restore the preceding terrain creation or replacement state. Closing the creation dialog with Cancel leaves creation uncommitted.
