Hello Ejas, if you want to learn about euro formats search in Wikipedia paper sizes.
 The basic is the format A0 = 1 m2 with a ratio of the square root of 2 = 1.4142136.......
Go to the CAD/BIM Blocks library in the site to find my file : PAPER SIZES A0+A1+A2+A3+A4.dwg for you to work in millimeters with some already set utilities.
Let us know if this helped or not.

I'd use 1.414. I doubt you need anything more precise. ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |
