Can we improve relationship arrow rendering in the semantic model view?

Hi kevincron​,

I do not think you are missing a setting here.

Microsoft documents editing relationships directly in the semantic model diagram view, including selecting the relationship line and changing properties such as cardinality and cross-filter direction, but I cannot find a documented option for controlling the actual routing/alignment of the relationship lines or arrow rendering in the web model view.

So for the behaviour in your screenshot, I would treat that as a diagram rendering/layout issue, rather than something you can currently configure.

A couple of practical things I would try are:

• move the tables slightly farther apart and see whether the relationship connectors reroute
• reposition the tables so the related columns are more vertically aligned
• compare the same model in Power BI Desktop to see whether the rendering is specific to the web model editor

But I would not expect those to be a reliable fix if the arrow orientation is being chosen automatically by the diagram layout engine.

Microsoft’s current guidance for the web model editor explains how to create and edit relationships, but I do not see any control for forcing connector direction or arrow orientation.

So if this is reproducible, I think submitting it through Fabric feedback / Ideas would be reasonable. The relationship direction itself is important information, and if the arrow visually points in an ambiguous direction then that is more than just a cosmetic issue.
