I have water pipe, water lateral and lateral point feature classes.  I'm trying to setup a check to flag any later points that split a water pipe.  To do this, I'm using the valency check where FC1 = lateral points, FC2 = water pipes and the valency at point location is set to operation and equal to 1.  Therefore, if a lateral point splits a line, it would be connected to two lines and be flagged.  The issue I'm having is that the check is including the water lateral layer in the check.  Therefore, if a later point is connected to a water pipe and a lateral, it gets flagged, even though the FC2 is set to water pipes (which I thought would then ignore the laterals).  How can I set the check to only look at water pipes and not water laterals.

Did you ever figure this out?  I'm attempting the same thing.

Hi Sachin and Lindsey,

If I understand this problem correctly, you are trying to find all water lateral points that intersect with Water Pipe only.

I would suggest a composite check with the following config:

Check1 : Feature on Feature

FC1 - Lateral Point

FC2 - Water laterals

Spatial Relation : Intersect

Not : true

Check2 : Feature on Feature

FC1 - Lateral Point

FC2 - Water Pipe

Spatial Relation : Intersect

Not : false

The output of this composite check will be Lateral Points that do no intersect with Water Laterals but intersect with Water Pipe.

Hope this helps.

Thanks,

Kumar Gaurav

My problem is very similar to the above but not exact.

I have a tap (point) where a service line meets a main.  I need to check to see if the main is split at this point where the service line, tap and main all connect.
