1 month ago The edge_type is primarily something we need to distinguish in the core. Besides this our default style uses this a a categorized symbology to give them a separate color.
It might be worth thinking about nice ways to control visibility by for instance looking at a column in the data model, or adding toggles. Though I think the requirements for this are different per model, and it probably won't be a priority soon. Also these is value to relying on QGIS as much as possible for these kinds of things.
For instance you can switch from a categorized to a rule-based symbology, and look at the from_node_type or to_node_type:
What A user wants to be able to toggle the visibility of links showing demand/return_flow on/off so the user doesn't get lost in all edges.
Why Demand/supply often represent (piped)systems that are not modelled explicitly. They will cross the actual water system that is being modelled explicitly. The user may get lost in a web of edges representing supply and return_flow
How Suggest to add a
demandedge_type, or something similar, that the user can switch off in QGIS, just as the user can toggle control-type links on and off
