Entities that are bridged with this bridge style will have a fixed distance between successive bridges. The bridges will be positioned symmetrically about the midpoint of the entity.
Add Spanish Bridges
Switch this option on if extra bridges are to be added at either end of the entity.
Spanish bridge width
Enter the required width of these bridges.
Number
From the drop-down list choose one of the following:-
- Odd number
- Even number
- Either odd or even
Odd number means that there will be a bridge at the midpoint of the entity and the rest of the bridges will be spaced from there. Even number means there will be a bridge half the required separation either side of the midpoint and the rest will be spaced from there. Either odd or even means that the maximum number of bridges possible will be placed on the entity.
Maximum length with no bridges
Enter the maximum length an entity can be without having bridges added to it.
Minimum land length
Enter the minimum distance that is required between either end of the entity and the first or last bridge.
Tie Bridges
These are generally smaller bridges that may be added to shorter entities. Select this option if they are to be used.
Width
Enter the required width of a tie bridge.
Maximum Length
Enter the maximum length that an entity can be before it has to have a standard bridge rather than a tie bridge.
Standard Bridge
Width
Enter the required width of a standard bridge.
Separation
Enter the required distance between successive bridges.
Intersections
Choose the required radio button to define what should happen when a bridge position coincides with the intersection between the bridged entity and another entity.
- Allow bridges at intersections
- Move bridges at intersections - Enter the required distance to move the bridge
- Delete bridges at intersections
