Wall Framing. In previous versions, Vectorworks did not recognize the core part of the wall. This made the wall framer unusable unless if you removed all the wall components.
In version 2012 the wall framer does recognise the core component of a wall and will use it for the wall framer. This does mean that you have to set up your wall styles to have a core component. Do not forget that wall cores do work with slabs, so it is worthwhile setting up your wall styles correctly.
