You can reposition Intermediate segments in an auto region dynamically. Use the Move Segment command and click and drag, or use precise distances. The movement allowed follows the conditions established by the current style and connection data. It also depends on the geometry next to the point you select for the operation.
As you drag the selected geometry, the system re-evaluates and updates adjacent route components. Route points that are automatically generated between points on selected geometry update when changes are made to a route.
