2. Click an alignment to attach the widening to. This is also known as the parent alignment.

4. Specify start and end chainages for the widening, either by clicking on the parent alignment or entering numeric chainage values.
5. Specify the offset width.
6. Specify whether the widening is offset to the left or right of the parent alignment.
