Hi
Can anyone tell me whether its possible to draw dotted lines, centre lines and hatching in layout
Yes for the dotted (and dashed and dash-dot etc) lines, yes for centre lines (depending on what you precisely want) no for hatching unless you do it manually.

Also, is it possible to get an A0 page size in Layout?
I'm pretty sure you can set any size you like. I've been using 36"x24" for my house plans since that matches my local print shop's big printer.
