Element	Description
Exporting	If the option of the column has been selected, all objects or all active objects of the selected network object type are exported.
Only active ones	If this option has been selected, only active objects of the network object type are exported. If the option has not been selected, all objects of the network object type are exported.
With z co-ordinates	If this option is selected, the z-coordinates are exported. Note This option is only available for the network object types nodes and links.
Directed	If the option has been selected, a separate object per direction is exported. If the option has not been selected, only one object for both directions of a link is exported. The attributes of the outward direction keep their names; attributes of the reverse direction all start with the prefix "R_". Note The option Directed is provided only for the network object type Link.
Node is starting point	If this option has been selected, the connectors start at nodes, not at zones. If the option has not been selected, the connectors start at zones. Notes The option Node is starting point is provided only for the network objects type of Connectors. For each single object the attributes of both directions are always stored. Attributes of the reverse direction all begin with the prefix "R_" (Fundamentals: Exporting shape files).
Columns	Via the button you can select the attributes you want to export per network object type. The selection is done in a separate window (Selection of multiple attributes).
Read layout	Click this button to read in a selection of attributes, defined per network object, from a list layout file *.lla (Saving a list layout). The attribute selection is displayed in the <Network object type>: select attributes window and can be edited there (Selection of multiple attributes).
POIs	You can limit POI export to categories. To do this, open the Select POI categories window via the Select POI categories button and transfer the desired categories.
Reset	Click this button to restore the default settings.

5. Confirm with OK.

For each selected network object type three shapefiles are saved (*.shp, *.shx and *.dbf) as well as a *.ctf file containing renamed attribute identifiers. For each selected network object type a projection file *.prj with the currently set projection is saved if they deviate from the standard setting (Visum = no projection).

Notes: To show the resutls, open the Shapefiles in ArcView or ArcInfo.

Strings are written out in UTF-8 format and a *.cpg file is created specifying this character set.
