Hello,
I made the mistake of building a multi-phase project in WaterGEMs as a full build-out, in base Active Topology. Instead, I want to have my new water infrastructure in phases, each in a different nested scenario, so that each scenario (5 in total) adds a new phase to the one before.
In my first sub-Active Topology, I have tried importing the full build-out, and then deleting out some structures that don't belong in this phase (phase 1), however, toggling between the base scenario (w/ base topology) and child scenario (w/ new topology), there's no difference in structures. WaterGEMs appears not to recognize the imported structures as New, while it does recognize new hand-drawn structures.
Is there a work-around for this? I have already reviewed the following article/video in full, by the way:

Thank you very much,

Hello Daniel,
To split your master network into phases you can use the "Active Topology" alternative.
If you have already created the master network, you have to identify elements (pipes, junctions etc.) for each of the phases.
I have prepared an example with a master network split in 3 phases viz. PHASE-1,2 and 3.
I have created separate child scenarios for each of the phases form my Master Network.
For each of the child scenarios (PHASE-1, PHASE 2 and PHASE-3); I created separate Active Topology alternatives and attache them to their respective scenarios (E.g. Scenario "PHASE-1" has "PHASE-1 Elements" as the Active Topology alternative)
Using the "Active Topology" tool under Home > Common Tools I made the relevant elements inactive for that scenario (E.g. For PHASE-1, I selected the PHASE-2 and PHASE-3 elements to make them inactive. Likewise repeated for PHASE-2 and PHASE-3)
The inactive elements would appear grey and cant be edited where they are not active. To make them completely disappear go to Tools > Options > Global Tab > "Uncheck Display inactive topology".
Now I can see only the elements I require as per my phase in separate scenarios.
Here is a short video demonstrating the above example;
Note: Be sure to set the scenario you are working in to "Current" before you start making elements inactive.
Hope this helps.

Thank you! Watching your video I realize my mistake was that I was -deleting- topology, not inactivating it, along with creating sub-nested scenarios & topologies. This does NOT work.
Hi Daniel,
Here is the relevant wiki article on Active Topology Management;
