Michael,
Thanks for the reply.
Its not so much a question of losing a specific function at this time. My situation is thus: I am a one-man shop. I have a single seat license of vanilla Autocad v2007 that is not on subscription. I also had a single seat of LDD which I have since cross-graded to C3D. That license is on subscription.
My question is, since I only need one seat but don't want to 'be behind' in vanilla Autocad or the civil vertical, is there any need to upgrade my vanilla subscription or will my C3D subscription keep me 'up to date' with all vanilla functionality (future file format changes, CUI/ribbon changes, future API's etc).
I know it is difficult to forecast what Autodesk might do, but I would appreciate opinions.
Thanks,
David
