Suspended Ceiling Generator builds a complete drop ceiling inside any room you draw: click the corners of an area in the 3D view (or follow a curve or mesh outline, columns included) and get a T-bar grid, tiles, lights, air conditioning, pipes, fire protection and electrics, rebuilt live as you change a setting.

The grid always follows the room. It snaps to the wall direction most walls share, in 90 degree steps, border tiles are cut exactly to every wall and column, and the layout balances the cut tiles on opposite walls like a real installer would.

Pick a design from a picture gallery (open office, hospital, school, retail, server room, hotel lobby, laboratory, stockroom, abandoned building), then change anything, or press Surprise Me.

9 ready designs
