Thanks people
Unfortunately none of this has worked....... still can not add a moulding.. I have been through many plans and none of them are allowing me to add a room moulding. I found only 1 that will allow me to add a moulding but its a very old 1 and I would have to do a lot of the defaults work in the program again to use that which we know can take a lot of time.
Any other ideas ??
