You can use this functionality to split legs at the boundaries of different surfaces so that you can allocate links to one surface.
1. If required, set the links active that you want to split, via
- the spatial selection (Setting network objects active/passive via the spatial selection) and/or
- filter criteria (Using filters to set network objects active or passive).
The selected links are active.
2. In the Network window, right-click the Links button.
The Links shortcut menu opens.
3. Select the Split links at surface boundaries entry.
The Split links at surface boundaries window opens.
4. If necessary, select the Only edit active objects option.
5. Select the surface types at whose boundaries links are to be split.
6. If required, select the Consider only surfaces of active objects option if you want to split links at active surfaces of the respective categories only.
7. Confirm with OK.
The links are split at all intersections of the selected surfaces and nodes are inserted in these places.
