There are currently some things needed to be added to the Corridor Object dialog to help communicate design intent a bit better to users (especially with Parametric Constraints):

The lack of information as to the rules linked to Parametric Constraints and the need to "hunt" though objects to see what is being applied reduces efficiencies in the use of this.

Some proposed enhancements include:

1. Adding a snap rule symbol (if station entry is ruled) next the Start and End Station fields in the Parametric Constraints section of Corridor Objects (and the other sections, like ECE, Point Controls, Template Drop and Key Stations) – see example attached

2. On selection of a specific Start or End Station that has a rule, the snap location is highlighted with a graphical snap symbol in the model (that only displays when the field is selected) - perhaps a zoom to option may be helpful

3. Append an entry counter to the Corridor Objects section titles to summarize number of entries in each section to avoid the user having to look through one by one – see example below

4. Integration of the Target Alias dialog into this dialog - perhaps that only displayed the current aliases and a "Change" button initiated by the user listed all Targets (so as to not reduce performance of the dialog)

5. Seeing that the undo command produces varying results, some users have also asked for a “Confirm Point Control delete”, “Confirm Parametric Constraint delete” etc. dialog when deleting corridor object entries

6. Likewise, we have many users erroneously changing values using up/down keys and then losing track of what's changed so many of our users have requested removal of the up/down key changing drop down values in Corridor Objects.
