The room object creates new surface layers around the surrounding walls, roof and ceiling. The room surfaces can be decorated independently from the rest of the house. The object can also generate automatically mouldings for the floor-wall edges and the wall-ceiling edges.

The surfaces are extracted automatically from the parent building object. The position indicator of the room object defines, which room space will be decorated. Moving the indicator to a new room moves the decorations as well. A room object moved outside the hierarchy of the building is inactive.

One room object added to the building

The room object has two special sub folders called floormouldingsample and ceilingmouldingsample. When an example section of a moulding is placed in either of these folders, the object automatically duplicates, stretches and transforms the moulding to travel around the respective floor/ceiling edge of the entire room. The example moulding can be placed anywhere in 3D space. Its object space must be properly oriented: the green y axis must point upwards and the blue z axis must point outwards from the wall side of the moulding.

[Note] Note
Repeating moulding structures, such as wooden panel walls, can be defined using a replicator object.

The Property window's Spec tab controls for the room object are listed below. Some of these options are available in the tool bar, too.

Object spaces for floor and ceiling mouldings

Room Options:


  • Texture Walls: Enables wall decoration. When set wallpaper surfaces are created.
  • Wall Range, From, To: When Wall Range is set, only the walls with indices between From and To are decorated. Indexing starts from the wall closest to the indicator.

[Note] Note
It is possible to add several room objects to a same room space, in order to apply several different textures to the walls. Only one room object should have the roof and floor surface creation enabled.
Two room objects applied to the same space

Wall Height:

  • Start, End: The relative height of the textured area of the walls.
  • Extend to Roof: Enables automatic wall surface extension to the limiting roof surface. This option can be useful, when the room space is not limited by a flat ceiling, such as attic rooms.
Start=0 and End=0.5 textures lower half
  • Wall-Roof Penetration: A tolerance factor, which helps to close the gap between extended wall surfaces and the roof.
  • Fitting Interval: The wall surface height is matched with the roof at every corner and where a roof line crosses the wall. If the roof has a complex or even a smoothly bending shape, a low fitting interval (such as 0.1 meters) may be necessary. This option defines a maximal distance between two fitting positions.
