OK, now I understand what you mean. The problem is that you don't see it live on the screen during typing how it will look, only after inserting. As a workaround you could draw a text box of your 3000 mm width first, maybe on a different layer. Then do your MText without any line breaking and insert it into the box. You will then see where it flows over the border. Open the text again with modify - properties and in the input window insert a line breaking with 'Enter' after the last letter that is within the box. Proceed so on, as you now will see where to insert the next line breaking.
I'm not sure if 'line breaking ' is the correct term in English. I guess you know what I mean.
