On a busy diagram, relationship lines can cross entities and each other, making the ERD hard to read. ERD custom waypoints let you bend a connector along a path you choose, so every relationship stays clear.
What a waypoint is
A waypoint is a fixed point a connector must pass through. By default Schemity routes connectors automatically, snapping them tidily. Add waypoints when you want manual control over a specific line.
Working with waypoints
- Add a waypoint by dragging from the middle of the relationship line - the waypoint is created under your cursor and you place it in the same motion.
- Move it by dragging to route the connector around obstacles.
- Remove it by double-clicking the waypoint.
- Straighten the whole line by double-clicking the relationship itself - it resets to its straight form, removing all waypoints at once.
When to use them
- Steer a connector around an entity instead of through it.
- Keep parallel relationships from overlapping into one unreadable line.
- Make an important relationship follow a deliberate, easy-to-follow path.
Waypoints are per context view
Waypoints are part of a view’s layout, not the schema itself. That means a connector you route by hand in one context view keeps its own routing there, independent of the main diagram and other views.
