Scala di stampa / print scale

Salve, sono alle prime armi e non riesco ad impostare le scale di stampa per stampe 1:100; 1:200; 1:50; 1:20.
Please help me


Hi Carlo - if the viewport is Perspective, you do not get to set a scale:



Thank you very much Pascal, but what about when you work in meters and centimeters?

For example in 1:50 scale, 1 meter = 2 centimeters on paper, how can I obtain this?

Thanks again

Hi Carlo - you can set any ratio you like -


I tried to do the same you did in the example but what I obtain on paper is wrong.
Maybe di I have to change something in settings?
