You will need to use a preset template
- Place the Meter and Flow valve and create the association
- Select the features
- Click Move on the Editor Toolbar, a yellow circle will appear in the middle of the two features
- Hold Control Key and hover the yellow circle, click and drag this to the flow valve
- Open Manage Templates
- Go to Flow Valve and generate a new preset template
This will use the flow valve as the insert point and the snapping. You can use the point and rotate tool to place the feature and rotate it.
I would like to see group templates support Junction to Junction associations, so please log the enhancement.
