How would one obtain a list of all the xref layers names?
I am in the process of brainstorming a lisp that would change certain xref'd layers colour to a shade darker.
Similar to locking the layer the xref is on in 2008.
My 'ctb is set up so that a shade darker of the colours will print lighter.
Thereby having the final plot show new and existing work, through the line weights.
Any help would be greatly appreciated....
