How the toolbox works
The toolbox rail runs along the left edge of the viewport. The top section switches the active interaction mode: Navigate, Sculpt, Select, Lasso, Draw, Cut, Paint, and Road. The lower section controls viewport visibility and camera helpers.
Tool shortcuts follow the same order: 1 Navigate, 2 Sculpt, 3 Select, 4 Lasso, 5 Draw, 6 Cut, 7 Paint, and 8 Road. The complete binding list is in Hotkeys.
Most tools act on the currently selected layer, feature, category, or collection target. If a tool appears to do nothing, first check the selected layer type and the status message at the bottom of the Editor.
Sculpt
Sculpt edits the active terrain layer. The four sculpt actions are assigned to mouse bindings: left raises, right lowers, middle smooths, and Shift + middle flattens by default.
The tool settings tray exposes brush size and strength. Brush shape is toggled between circle and square with the C and F keys. Size and strength can also be adjusted with keyboard shortcuts.
Sculpt changes are stored as editor terrain overrides and terrain grids. They do not overwrite the original DTM asset. Reimporting terrain clears those sculpt overrides and terrain-shaping modifiers, as explained in Importing and Reimporting Layers.
Sculpt only works when a terrain layer exists. If the project has no terrain layer, import a DTM asset or create an empty terrain layer from the Layers panel.
Select
Select is the main editing mode for existing vector features, markers, placed buildings, road assignments, and road junction parts. The exact handles shown in the viewport depend on what is selected.
For vector features, click a feature to reveal its vertices. Vertices can be moved, inserted, or deleted. Hold Shift and click a second polygon to merge compatible polygons. If a feature has been rectangulated, shape editing can be restricted because the modifier owns the generated rectangle geometry.
Selected features are also highlighted in the Objects panel, where you can inspect the layer, category, tags, and attributes.
Lasso
Lasso selects multiple vector vertices by drawing a freeform area in the viewport. All eligible vertices inside the lasso are selected when you release the mouse.
Use it to move or delete a group of vertices on a line or polygon edge without touching the rest of the feature.
Draw
Draw creates new vector features in the selected draw target. Points commit on click. Polylines and polygons are built vertex by vertex, then committed with Space or the configured finish-drawing key.
The target layer and category are selected before drawing. If the project needs a manual vector asset for new geometry, the Editor creates or reuses the project manual vector asset behind the scenes.
Some collection workflows also use Draw. For example, the water workflow can switch you into Draw so you can create or adjust a footprint before applying a water surface collection.
Cut
Cut removes parts of vector polygon features. Brush mode cuts with the current brush shape. Line mode cuts along a drawn path. Complexity controls how many segments are used for the brush trace, so higher values make smoother cuts but add more geometry.
The Editor reports skipped cuts in the status message when a target cannot be split cleanly. This usually means the selected geometry is invalid for that cut path or the cut would leave unusable fragments.
Paint
Paint writes values into an editable manual raster layer. Static imagery layers, terrain layers, and vector layers are not paint targets.
Manual raster layers can be grayscale, RGB, or indexed. Grayscale stores a single intensity, RGB stores colour, and indexed stores numeric labels used by workflows such as foliage. The layer is created from Layers.
Paint commits update the manual raster asset content. A paint lock mask modifier can block painting under selected vector polygons or buffered lines; modifiers are explained in Modifiers.
Road
Road mode configures road surfaces, lane markings, and detected intersections. It works with vector line features that have buffered road geometry, usually created with a Buffer or Roadbed modifier.
To apply a road surface, select a road collection in the Collections Panel, select a compatible polyline or category, choose the base texture and lane count, then apply the road. The Editor stores road assignments in project metadata.
When intersections are detected, Road mode shows junction markers. Select an intersection to configure connected road priority, crossing markings, stop markings, direction markings, sign markings, and blocked slots. Road traffic side is controlled by Editor project settings.
Visibility toggles
The lower portion of the toolbox rail contains buttons that show or hide classes of content independently of which tool is active:
- Grid — show or hide the terrain grid overlay.
- Polygon overlay — show or hide all vector feature shapes on the terrain.
- Textures — show or hide terrain textures (polygon shapes remain visible).
- Meshes — show or hide placed 3D objects such as trees, buildings, and water surfaces.
- Connections — show or hide derived connection previews for road networks.
- Raster opacity — appears when a raster layer is selected; opens an opacity slider for that layer.
- Bounds — show or hide the playable area boundary overlay.
- First-person — toggle ground-level camera view.
- Reset camera — return the camera to the default overview position.
