The Cogo Stationing plug-in allows the user to select an alignment and then cogo points. The nearest perpendicular intersect is used from each cogo point and the stationing at that point along the alignment is added to the description field of the cogo point. The offset can also be added to the description field of the cogo point.
If no perpendicular intersect is found along the alignment then no stationing is added to the cogo point description. The added stationing will not replace any text in the description box unless it is an existing stationing with the delimiter '+' (ie. 0+999.99). In this case it will replace the old stationing with the updated station value. Otherwise, the existing text in the description field is placed before the stationing. The formatted stationing string is the same as the user's stationing style attributed to the alignment.
If the user chooses, the offset can also be added to the description field, either alone, or tagged on after the stationing.
