Hi Katie,
Yes, we have been a Minicad/Vectorworks-only company since MC6, and thus have a huge collection of Minicad files consisting of many different version types. My point being, whenever we do work for a Client whose drawings were done back in the MC6 days, we have to load up Classic, Vectorworks 8, import, save, then finally load Vectorworks 12.
I realise certain aspects of these drawings may not be exported, but to at least be able to import lines (as most of our MC6 drawings were purely constructed of that) would be a great time saver.
I realise it's not really a big issue, and I wouldn't be surprised if we were entirely alone in this boat, but all the same it'd be nice to be able to import mc6 from 12.
