Problem: The number of route features in a coverage is being reduced by various commands

Description

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.

Cause

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:

Code:
Arc: tables
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.
