The first video deals with plan views.
This next video is about ceiling plans and framing plans.
The last video is about site and roof plan views.
My session of Jing ran out of memory right as I was about to wrap the third video so I left it as is, lazy guy syndrome. I hope that between their video and these that view range starts to make more sense!
