ArcGisPro 2.5
I'm to a stage in my testing where I've added my own data to the Address Data Management gdb and I'm modifying the address rules for the various feature classes. I can add an Address Point, but I don't get a resulting Site Address Point.
I made only minor modifications to the Create Site Address Point Rule in the Address Points design:
- Changed the left/right from and left/right to field references to the proper field names of my Road Centerlines
- Changed the reference to the road centerlines feature class to the name of my Road centerlines
- See lines 29 through 33 and Lines 105 & 108 respectively in script below
Is the site address point spawned through the relationship class 'AddressPointHasSiteAddresses'? It does not appear to be. I'm not sure what is missing to cause the Site Address Point not to be created.
// This rule will create a new site address point when an address point is created along a road
// The site address point will be offset from the road by the distance and direction defined in the address point feature template

// Positive distance is to the left of the line. Negative distance is to the right of the line

That should just about do it....
