Column Description
PathFilename Path and filename of graphic file
CoordTRX Coordinate top right (x): Coordinate (x) of the upper right corner of the graphic
CoordTRY Coordinate top right (y): Coordinate (x) of the upper right corner of the graphic
CoordBLX Coordinate bottom left (x): Coordinate (x) of the bottom left corner of the graphic
CoordBLY Coordinate bottom left (y): Coordinate (x) of the bottom left corner of the graphic
CoordBLPt Coordinates bottom left: Corner point CoordBLX and CoordBLY. When you change one value, the value associated with it in CoordTRPt is automatically changed as well.
CoordTRPt Coordinates top right: Corner point CoordTRX and CoordTRY. When you change one value, the value associated with it in CoordBLPt is automatically changed as well.
Level Name of level
ZOffset Z offset: Height relative to the height of the level. Avoid values between -0.2 m and -0.5 m.
TileSizeHoriz

Tile size horizontal: Width

The background image is loaded tile by tile. Tiles are recommended for large networks with large background images. In 3D mode in particular, the duration for opening the graphic files depends on the file size of the graphics files.

TileSizeVert Tile size vertical: Height
Res3D

Maximum 3D resolution for displaying background images in 3D for raster graphics and vector graphics. This depends on your computer's graphics hardware and the number of currently loaded background images.

2.  On the list toolbar, in the Relations list, click > Level.

The attribute and attribute values of this network object type are shown in the list on the left, which consists of two coupled lists.

The list on the right contains attributes and attribute values of levels allocated to the network object selected in the list on the left (Using coupled lists).
