Terrain Tools

Shape terrain around anything you build. Select parts or a whole model, pick a tool, preview the result see-through, and apply in one undo step. CONVERT Turn selected parts into terrain — per part, or merged into one landmass with gap closing and interior solidify. SKIRT Raise terrain up to the underside of a road or platform so it stops floating, with sloped aprons that blend in. TUNNEL Carve clearance above a path — flat or round ceiling that follows each segment, so a curved road bores a curved tunnel through hills. FLATTEN Level terrain to a part's bottom plane within a reach around it — hills carved away, dips filled, in one pass. MOAT Dig a water channel along the selected parts and fill it to a level. PAINT, SMOOTH & CUT GRASS Repaint the terrain material under builds, soften harsh voxel steps, or swap animated Grass for a blade-free material so it stops poking through floors. See-through preview: green = terrain added, red = removed. Full undo/redo.
