Possibility to create levels or floors and to define parameters of the same one, for example, height of the slab of the level, height of the walls for that level. When the level is created, it creates a visualization layer for that level and all rooms, walls, windows, doors, etc., for that level. The total height of the level would be the sum of the slab, plus the height of the level.

Possibility of creating slabs and defining their height, as well as their material, concrete, cement, wood.

Possibility of adding an option to choose which level the created object belongs to. If I create a window, I must choose for which level is that object, for example for level 1 or 2. Then automatically that object will be positioned at the height of the chosen level, in the display layer corresponding to the level, and so on.

Possibility of creating hollow domes or geodesic structures, with the possibility of defining the width of walls. Nowadays there are several forms of constructions more advanced than the classic straight walls.

Possibility of creating roofs in the style of a dome, where the height, length, width and size of each tile can be defined. Oriental architecture uses this type of roofs a lot.
