I'm so glad I posted this topic here. Everyone who replied has contributed at the very least in helping me find motivation for going forward with this task. At the moment I've sent him back to basics doing 'online tutorials' and working with the sketcher and the simple parts. Future progress will be at a slower and more methodical pace. I think the main thing I've figured out is that I need to impart to hime that HE is responsible for actually learning SW - not me. The things he has stumbled on or figured out himself are the ones that stick best.
thanks,
Zander
