Relief > Calculate > Merge

Use Relief > Calculate > Merge High and Relief > Calculate > Merge Low to merge a new relief with the active relief layer, so only the:

• highest points are kept; or
• lowest points are kept.

Note: The Merge High button and Merge Low button on the Relief Editing toolbar and on the Shape Editor panel are shortcuts for these menu options.

To merge a new relief with the active relief layer:

1. Create a circle and a rectangle vector and centre them in the model.

   

2. Flood fill the circle vector in blue.

   

3. Double-click the blue circle. The Tool Settings: Shape Editor panel is displayed.
4. Select Round to create a rounded profile for the blue circle.
5. In the Relief Combine Mode area, select Add. The rounded shape is added to the active relief layer, and displayed in the 3D view.

   

6. Click Apply.
7. Click Cancel to close the Shape Editor.
8. In the 3D view, flood fill the rectangle in red.

   

9. Double-click the red rectangle to display the Tool Settings: Shape Editor Tool panel. The window in the Shape Editor panel is red.
10. Enter a Start Height of 2.
11. Select Merge High. The plane is merged with the rounded shape so that only its highest points are kept.

    

12. Select Merge Low. The plane is now merged with the rounded shape so that only its lowest points are kept.
