User interface

The main screen combines a central 3D viewport, a menu bar, a general toolbar, a mode-specific toolbar and dockable utility windows.

Edit modes

Button	Mode	Behavior
	Sculpt	Enables terrain editing and the sculpt/ocean/lake/country/sound toolbar.
	Footpath	Shows footpaths. In the supplied source the dedicated footpath toolbar currently contains no editing commands.
	Object Placement	Opens the Catalog and LHX Tree panels and makes the Object Attributes window available.
	Script	Script-oriented mode; the Camera Info window is shown automatically. Script editing itself is performed in the LHX Script window.

Selection modes

Clicking opens four selection operations:

New	Replace the current selection.
Add	Add the polygon contents to the selection.
Subtract	Remove the polygon contents.
Intersect	Keep only the overlap with the existing selection.

Viewport controls

• Mouse wheel: zoom.
• Right-drag: orbit; middle-drag or Space+left-drag: pan.
• With the Orbit/Pan tools active, left-drag performs that camera action.
• Q/E rotate yaw, R/F pitch, W/A/S/D pan, numeric keypad +/- zoom.
• Ctrl+Numpad 0 resets the view; Ctrl+Numpad 5 switches to top view; Ctrl+G flies to a coordinate.

Status bar and windows

The status bar shows context messages, cursor XYZ coordinates, used/max landscape blocks and Java heap usage. Dockable windows include Block Inspector, Object Attributes, Catalog, LHX Tree, LHX Script, Camera Info, Edit History and Console.
