Pat,
Thanks for getting back to me - I knew how to do that - just!
I have created a Standards Drawing which has all of my normal Classes, Layers etc within it.
I have also created a WS that quantifies by Class as I draw to quantify things.
Being a dumbo the WS I fiddled with to get it working correctly in the Standards file I wanted to take it back into another drawing with some altered Classes.
So all I wanted to do was check the Classes worked correctly simply.
In future the WS will live in the Standards file - but if you have script for future purposes it could be really handy.
Thanks again
