Engineering Drawings - Line Colours in SW

Hello,

I am posting this to ask a couple of questions in regards to engineering drawings and the SW standards based around this.

1) How do you make the smart dimensioning come out black on the printer instead of grey, if so should it be black or grey anyway?

2) How do I adjust line weights quickly and what are the British standard for line weights etc?

3) Should dimensions be centred along the measurement line or aligned with other dimensions on that axis?

Cheers,

Tom Haslam
