QUBIC - Modular Builder

QUBIC is a fast and intuitive editor tool for constructing architectural designs in Unity using modular prefabs.

QUBIC lets you draw rooms like in a map editor, and builds the entire structure around them: walls, floors, doors, windows, stairs, props and furniture.

Just draw or move rooms in the scene view - everything updates instantly. Doors and passages are placed automatically, furniture spawns according to rules, and multi-story buildings stay connected by logic, not by hand.

No need to place each wall, align doorways, or manually decorate interiors - QUBIC handles the structure so you can focus on your ideas.
