I have some drawings which were created in ADT 2006(I think), using the BS-1192-Descriptive Layer Standards. This was great as walls/doors/windows etc were automatically put onto A-Wall-G/A-Door-G/A-Window-G.
Since installing 2008, any walls/doors etc go automatically onto BS1192-Cisfb layers (A210G/A315g etc).
How can I change the default layer style back to Descriptive? I have tried purging the layer key style for Cisfb, and dragging Descriptive from another drawing, but all wall/door/windows etc just default to layer 0.
Any help appreciated!
