This option is used to convert 12d Water (Drainage) Strings into individual Points and Lines for each Node and Link within the network.
This process is necessary when exporting data to GIS as most packages can’t handle having Node/Link (Segment/Vertex) attributes.
The panel splits the stings into their individual object elements and moves all current attributes from the Node/Link (Segment/Vertex) level up onto the “String Attribute” level.
Further manipulation of the attributes can then be under taken as require. This demonstrated on the “Export ArcView SHP file” Wiki page.
