I've started drafting in Sketchup. The free basic version is more than sufficient and has lots of free downloadable models and templates. Sadly, I've never had opportunity to learn Vectorworks or any other drafting program.
That said, nothing beats hand drafting. Not only did my drafting class in college drastically improve my handwriting (I failed my first handful of projects on handwriting alone), it was great drawing practice and really improved my art overall. It's hard to describe, but there is some additional benefit to the kinetic aspect of designing on large sheets. Perhaps, for me, movement while creating helps my brain sort out what goes where in a way that is just lost on a static screen.
