Those objects which are already placed in a room or exterior scene can be used to align other objects. Moving an object you will recognize that in orthogonal direction there is a higher “gravity” than in any other direction. So moving along X, Y or Z axis is simple. Those objects (bounding boxes of furniture, walls, luminaries room elements), which are already in the scene can create automatically temporary help lines to align other objects to.
Fig. 269 Automatically by the walls generated temporary help lines
In the screenshot you can see the red help lines which follow the direction of the tilted walls. These help lines are generated when you move with one object (e.g. luminaries) for a short while above any other object (e.g. wall). The help lines are visible until the left mouse button is released.

Here you can see help lines generated by the cube. Now it is pretty easy to align cube and luminary.
