====== Elevation Lab Window ======
{{:manuals:terraineditor:reference:temain:te_elv_lab_0.jpg|}}

This window's purpose is to help you edit the elevation data of the loaded [[falcon4reference:terrain:theater.lx_ox_files|L2]] file **or** the [[falcon4reference:terrain:theater.lx_ox_files|L0]]/[[manuals:terraineditor:reference:file_formats_reference:elv_file|ELV]] file. There two methods to change the elevation data.

===== Direct Replacing =====
By setting the ''Elevation'' value in the ''Click and set Elevation'' frame and then pressing the ''Activate'' button, you can click directly on the tiles in the [[manuals:terraineditor:reference:temain:theater_window|Theater Window]] and change the elevation of the tile. The mouse cursor of the [[manuals:terraineditor:reference:temain:theater_window|Theater Window]] will change to an arrow (pointing SE), to indicate this action.

===== Area Elevation =====
You can select a rectangular range of tiles on [[manuals:terraineditor:reference:temain:theater_window|Theater Window]] and change their elevation with one click. To do this, you first press the ''Set the Area'' button and select the range of tiles. To indicate this action, the mouse cursor over [[manuals:terraineditor:reference:temain:theater_window|Theater Window]] will change to a cross and the selected tiles will be overlay-ed by a semi transparent gray layer.

<box 100% left round blue>{{:t1.png |Tip}}The selection action is press-drag-release, over the [[manuals:terraineditor:reference:temain:theater_window|Theater Window]] and not two clicks as it is while [[manuals:terraineditor:reference:temain:home#Save / Export / Import Area|Importing/Exporting tiles]].</box>

After the Area is set, the ''Recommended Elevation'' textbox will be populated by the mean elevation of the selected tiles. If you want a different elevation to be applied to the selected tiles, you can change this value. After that, you just press the ''Set'' button and change the elevation of all selected tiles.
