Editors are there to add, modify or remove objects and settings for: Way, Stream, Modal Split, Poly, Line, Sign, Zebra, Stop, Speed Breaker, Control Area, Priority Control, Signal Control, Simulation Settings and BGM (Background Map).
Each editor will have a close button (a small button with ‘x’ on it, top right corner), a ‘Done’ button and a ‘Discard’ button.
Example: Way Editor
Signal Editor
Polygon Objects Editor
Once data is entered or modified, pressing the Done button will use the data. The Discard button will restore to the previous data just before the editor was opened. The Close button will do the same action as the Discard button and then close the editor.
