Displaying the position
Select View > Show position to toggle the display of the position of the vertex under the mouse in the top left of the viewport. The x, y,z coordinates are displayed in meters and depend on the quad size of the grid.
For example, the vertex at the top left of a
terrain has the coordinates x = 0, y = 0.
- If the grid is 1024 x 1024 with a quad size of 1 meter, the
bottom right corner of the terrain has the coordinates x = 1023, y
= 1023.
- If the quad size is 2 m, its coordinates are x = 2046, y =
2046.
- If the quad size is 50 cm, its coordinates are x = 511.5, y =
511.5.
Displaying the mannequin
Select View > Show mannequin to display the mannequin or click on the icon in the toolbar to activate the option.
The cursor changes to a mannequin.
When the resolution of the terrain is insufficient, i.e. when the value of terrain's quad size is greater than or equal to 10 meters, the option is disabled because the resolution is obviously not adapted to the size of the mannequin.
When you click in the terrain, a mannequin of 1.90 meters, or 6 feet and 3 inches tall appears in the terrain.
The icon turns red

Clicking a second time on the icon hides the mannequin.
