I wish the whole subscription issue clarified. I recieved a cryptic letter
announcing an almost doubling of my ADT 3.3 subscription fee and some vague
mention of a Building Systems. Called my local rep. He'd not seen the
letter (I faxed him a copy). He wasn't sure what to make of it either.
I've also searched the Autodesk web site and not found a single, clear,
concise discription of how the ADT is part or not part of the Building
Systems, or how the extra fee is going to bring value to my subscription,
short of paying extra when upgrade time comes around.
