Hi Rob/all users

1. Of course the first answer will be 'it depends' but as dumb of role, what is the max scale (or min, depends how u call it) its advised to make a drawing. 
I.e.
Of course there is a maximum paper width (1.2 metres i think) for plotters. If we do not want to print on several pages, what us the advised maximum grid/dimension on the vertical side, whioe the elements/lines/labels/products will still be readable ? (Again, depends on your eyes, and how much small u want your drawing, but for usual people)

2. Is that possible to ask to have a kind of 'show paper limits' on the drawing (like in excel where u can see the print area in white), or u have another idea / woraround ?
We might miss something or trying to make something wrong.

3. We try to print a selection (select. Print selection), but it do not work. What are doing wrong ?
