System Details: Pro3.1, water distribution foundation v1.3, coordinate system New Zealand Transverse Mercator, units: metres
I'm getting unexpected associations using B_Rules table and Create Association Records GP tool.
I have generated some test data inside a foundation water distribution asset package consisting of service connections and service meters. The service meters are offset from the connection points in distances from <1m, <5m and <10m.
In this attempt, I have nominated 1 as the "Distance for associations" in the B_Rules table. I would expect that only meters within 1 m of a service connection would have an association record generated.
Below is a screengrab of my B_Rules table, noting that there are only distances nominated for meter to service connection, and not meter to meter. The rest of the table's distance values are <Null>:
Below is a screengrab of my meters and service connections. Red circles are 1 m buffers around the service connections that I'm testing. Three meters are within a red circle and I expect them to have associations generated when I run the Create Association Records GP tool:
The tool runs successfully, but too many associations are generated. In addition to the three I expected (green circles), an additional four (red circles) were generated that connect meters with other meters:
One pattern I note is that meters that are not connected to anything are >5m away from the next device, otherwise this looks random.
To prevent the association records from being generated I was able to put in a distance of -1 for all the undesirable meter-to-meter connectivity (highlighted rows below):
Is this a bug? If not, can anyone point me towards additional documentation on how this distance field is supposed to work?
Thanks
