Problem: The number of route features in a coverage is being reduced by various commands
After executing commands such as PROJECT, CLEAN, or CLIP on a coverage containing route features, the number of route features in the output coverage is reduced.
These commands require the User-IDs of route features to be unique; otherwise, route features will be merged based on User-IDs.
Solution or Workaround
Calculate the User-IDs of the route features in the input coverage to be unique. One approach is to use TABLES to calculate the User-ID of each feature equal to the record number or the internal number of the feature:
Tables: select roads1.ratbus
Tables: calculate bus-id = bus#
Once the route features have unique User-IDs, no features will be merged when using the commands mentioned above.
