In the model view, select the alignments vertex where the new chainage equation will be applied. Note:
|
| Distance | The two dimensional distance along the alignment from the start of the alignment. |
| Back Chainage | The chainage of the selected vertex using the previous chainage equation. |
| Chainage | Type the new chainage at the vertex. |
- Select an alignment in the model view prior to clicking the command to automatically select the Alignment.
- The Start Vertex row must be retained.
- Each vertex must have a chainage.
- Only a single chainage can be applied to a vertex in an alignment.
- The vertex column is not filled if you pick a vertex that is not used for the alignment.
- The vertex cell is highlighted and the distance and back chainage cells are not automatically populated if the vertex specified is invalid for the selected alignment.
- The chainage cell is highlighted if a chainage has not been input for the vertex.
