With CadnaA it is not possible to export the type of Embankment object directly as a shape:
However, it can be exported as a shape by turning the Embankment object into a Screen-type item and by performing the following steps:
1) Write the 3 attributes ("Relative Height (m)", "Pending 1" and "Top Width") as String-type variables within the MEMO field of the Objects.
Repeat action with the attributes "NEIG" (Pending1) and "KRBREITE" (Width).
2) Turn the Embankments into Screens.
3) Within the Display attribute table (user-defined), add 3 lines and assign previously added MEMO variables.
4) Export the Screens as ESRI Shape Files (*.shp).
