Use the Parcel Map technology for topology.

Lines have From Point and To Point.

Polygons have own lines.

Hello Marius,

Could you please provide more information? 'Map Topology;, which is exposed on the editing ribbon tab, only respects visible features.
The parcel fabric uses a 'geodatabase topology' which keeps features aligned regardless if they are visible in the map or not. 
The geodatabase topology is controlled by the parcel fabric and is fully configurable.

Hi Amir'

First to say I was told by Dennis that we might have some topology issues in our geodatabase.

At this time we can't move Points with topology, we can't Align Features or Parcels.

When I used Align Parcels either way align to surrounding parcels or if I switched topology the result was dramatic.  I got a lot of errors after Validate Topology.

The most important especially for Historic Legal Lots the Point and some lines were tight together but the polygon vertex and some other lines were at a different location very close but throwing an error.

Took me hours to fix the Fabric.

On the other hand after running Validate Topology, I got extra lines and Points on some curves which could NOT be discarded and I had to trash my version and loose HOURS of work.

If the topology doesn't work in your geodatabase we have to get to the bottom of it, potentially with assistance from technical support.

Technical support will most likely make sure your parcel fabric topology is enabled, your topology was published properly, and that your map is not the culprit.

I have trouble understanding if this is an idea for new functionality that others can vote to promote or a question. 

Please clarify

Thanks,

Amir

If the 'From' and 'To' points are of interest, they can be calculated using an Attribute Rule, but there is no intention of using attributes to define the topological relationship between points, lines and polygons. This approach, which was used in ArcMap has a lot of 'overhead' as an update (=insert, update, delete) to any of the trio (point, line, polygon) has a cascading effect that requires selecting the features in the database (SQL query).

The spatial relationship in the new parcel fabric is based on spatial coincidence. This approach is more scalable and does not require things like 'line-points', radial lines, and curve center points.
