When drawing new segments, or moving segments around, the editor will automatically make junctions.
- For new roads, if you start and/or end the new segment on an existing segment, a junction is created at the location were you start/end the new segment
- For existing roads, if you move the start or the end of a segment onto an existing segment, a junction is created
- If you move a junction to an existing segment or junction, all roads connected will be part of the junction.
