Robert Green seems to have answers for everything – if you haven’t subscribed to his CAD Manager Newsletter yet, you should!

It’s important to note that this change will affect only those customers who already own perpetual licenses of standalone desktop software; it does not affect customers using Autodesk product suites or those already on a desktop subscription plan or using cloud services.
Anyone who has been through the Land Desktop transition to Civil 3d should understand that statement is probably best read with a big YET inserted at the end…
