   Hi,

I need to print 1:1 big pieces plans on polyester (>A0). For this purpose, I hire a professional printing service. They have 900mm or 594mm large polyester rolls, so in practice, there is no limit for the length, which is what I need for 3 meters long pieces.

I am new to FreeCAD. I could see that to get 2D plans from a 3D model, I have to use the Drawing module. But the biggest it proposes is A0, requiring for my use case 3 pages, which is not desirable.

In addition, the printing service company requires pdf only.

So:
How could I get 3 meters long pdf exports at 1:1 scale precisely (no adjustments)? If it is not possible, I would fall back on A0.
Is it possible to configure A0 overlaps so that Drawing manages itself exports/prints in several pages with connection marks? I have tried to project a selected 3m long piece in an A0 sheet with scale 1, but it has fitted it in the page.
Of course, I can install any opensource additional software as an helper.

	Hello lalebarde, you should talk with your professional printing service to know the LENGTH of their polyester roll. Then you make a 3+ meters long special paper size, you do your PDF from AutoCAD VERIFYING THE SETTINGS because PDF will give you some % more of margins and communicate the exact 3m+ paper size so that they can : declare a special paper size on Windows to print it correctly. Personnaly I would place some kind of o ruler ( r?gle gradu£e ) on the very first side of your paper size to come out of the printer for a quick test before spoiling a big 3 m polyester "paer size". Please tell us if this helped or not and if you got your polyester OK. Have a good day. I don't know FreeCAD but on AutoCAD you have an idea of the real scale of the printed area with : Plot scale , fit to paper , scale : 1 mm = 1 unit ( if 100% at scale 1/1 ) Edited by philippe JOSEPH - 24.May.2020 at 16:24
