Roof on plane

The roof over a plane draws a triangular prism above the metrics, the top of a roof - on the center if the metrics can be considered as a tape (over of 5-points is drawn always).

The height of a roof can be a constant or can be taken from specified semantics of map object. At zero height it is not drawn.

The height of a roof shift over a surface can be a constant, can be taken from semantics of object or the roof can be located above other part of the image (Relative radiobutton).

The roof over a plane can be located along the metrics as follows:

- On a relief;

- The top is horizontal;  

- Without taking into account a relief.
