Build, select and move

A floating platform

1. Choose Brush → Fill.
2. Set Place on → Fixed height above the view, then enter the platform’s bottom height in metres.
3. Set Width, Height (thickness) and Depth, then click the grid. No supporting block is needed.

Move a whole volume

1. Choose Select → Drag a volume. Set the Bottom and Top heights to include the blocks you want.
2. Drag across their footprint. Use Top view to see the whole area.
3. Release, then drag a coloured arrow. The whole selection moves as one undoable edit. Use exact bounds for hidden corners.

Selection edits base voxels. Placed prefabs and entities keep their own placement.

In a playtest, Q activates your equipped utility and H shows match controls. Esc returns to the editor.
