Thanks Kieran, it's a real hard slog for a nOOb though! Sheesh, his next 7 mins took me one hour to work out, boy am I getting used to the undo key. At one point I ended up with a very crooked looking building, but that forced me to get lots of practice getting verts back in line. Seriously, I do not know how the pro's do it. Ha, I've just seen Pete's reply too..yeah, I love Cntrl R, almost as much as Cntrl X.. Eventually I'll be using that to a lesser extent! Bugger, now the simplest question you'll see for awhile - command for nominating a set of linked vertices as a new object? And what about selecting all of a new set of surfaces, built separately from the main model, ready to be plonked into it, easily? I've tried B, and select linked, but it takes a few goes to get it all - is there a secret way to do, it, or is it just a well known bug?
