Locked Vehicle Units
When a Vehicle is 'Saved As' or you import a Vehicle Unit in from a different source the Vehicle Unit(s) are locked.
This is a feature so that if you wanted to test different combinations of Vehicle Units or test changes to a singular unit in a combination you can be sure that the other vehicle units properties are the same.
For example, if you wanted to test Prime Mover dimensions for a set of trailers. However each of these you can edit the Prime Mover properties while knowing that the trailers are the same.
To unlock a Vehicle Unit you can right click any component or use the panel on any component. You will also be prompted in case you want to unlock the entire Vehicle rather than doing every Vehicle Unit individually.
