Guidelines on data changes and locks.
Library files supplied by Autodesk can only be edited once they have been copied to the Pool. Thereafter, any changes you make to the library data will affect all Autodesk Vehicle Tracking entities that use it. Note that vehicles cannot be edited after they have been used in a path.
You can edit libraries that you create. However, in order to prevent accidental changes, they will be locked when you close Vehicle Tracking, and you will need to unlock them to make any changes.
