There is one web site I always check out for architectural technology and Vectorworks:
This week the author, Steve, joined an online demonstration of BIM and Vectorworks. The review is well worth a read. http://blog.konstrukshon.com/?p=1595
Steve also has an article about CAD Class tables and what classes should be used for. Again, well worth a visit. http://blog.konstrukshon.com/?p=1569
Just tell Steve I sent you.
