Here's a list of all the ArcFM AUs and what they do: Special Autoupdaters
That Segment Split AU gives you more fine tuned control over if a point feature should split a line feature or not. If the AU is applied, a newly created point feature will split the line. If the AU is not applied, a newly created point feature will not split the line.
Thanks David, My question relates to the behaviour when the features participate in a geometric network; in one scenario where the edges are simple and another scenario where the edges are complex.
The ArcGIS documentation states:
"If you snap a junction or edge along a simple edge, the edge being snapped to is split both in the logical network and in the geometric network, giving you two edge features. If you snap a junction or an edge along a complex edge, that edge is split in the logical network but remains a single feature in the geometric network."
Is it compulsory to use the Segment Split AU in order to get this core ArcGIS behaviour working in an ArcFM gdb?
Does the Segment Split AU alter this core ArcGIS functionality?
Can you use the Segment Split AU to override this core ArcGIS behaviour? Your documentation implies this is true for simple edges:
"Note: If you remove the ArcFm Segment Split AU from the point feature class and the SPLITTARGET model name from the linear feature
class then the linear feature will not split."
We are seeking clarity on the precise behaviour in these scenarios.
The Segment Split AU only affects complex edges. ArcFM does not and cannot change the splitting behavior that occurs when using simple edges (Esri does not provide an event for ArcFM to hook into).
That said, I am not certain that ArcFM was designed to work correctly with simple edges. You may want to speak to support about this.
That's what I needed to know.
Just to clarify we do support ArcFM with simple edges. However the majority of our customers do use compex edges with electric (and utility) geometric networks.
