screen representation scale

[zetadierre]

Good evening,

the real scale zoom command is very useful because it allows you to stay less "extracted" while working. However, it is easily understood as, putting an a1 as a print area and putting real scale, this command approaches only vaguely to the real print sizes.

Is there something more to know? I would be useful to understand how to correctly display on the screen what I am creating to a dimension much closer to the real (I have to do urbanism and with 5000 10000 and 20000 I don't have much dimisticity :-d )

Thank you.

the real-scale zoom command was particularly accurate at the time of the crt screens (tubo catodic) that had a fixed resolution of 72dpi.
Now with the led monitors this ratio is no longer possible, since changing the number of pixels that the monitor can reproduce, changes also the measurements of the objects represented on the screen. if I do not err, today you typically work with resolutions of about 110dpi (but I am not sure about the value!).
the command therefore is no longer able to give a really "real" scale and should be renamed almost real scale;-)

I believe that if you measure the height of the screen (in my case with the 17 inches the useful height is about 20 cm) and you see for example 1\3 of area of an a1 in height (which is 59,4) then maybe you approach. I think I'll do that. otherwise if I wanted to "set" something to my end... without obviously getting into things too risky, would you have any advice to give me?

I think you should draw an object, say a square 10x10cm in scale 1:1 and find which zoom factor is drawn on the screen with those measurements, using a ruler or other. at that point you should mark the magnification factor to use instead of 100%.
It's an empirical idea that came to my flight (and I'm not even sure it works). Let us know if you can.

in real scale a square of 10 cm side 1:1 measures on the screen exactly 5.5 cm...

then I can safely say that

on a macbookpro 17 inch unibody at resolution 1900x1200 the real scale is obtained by setting the zoom factor of 185% (tested by placing the bright screen of a regional card at 10000 imported in vector under the print at 90 grams of the same file at the same scale).

Yeah!!!:biggrin::biggrin::biggrin:

which means that your screen is operating with a resolution of about 130dpi. on my monitor, for example the square measures 7,3cm, so I have a resolution in dpi less thrust.

easy that if you have a fixed you have the greatest monitor at the same resolution, I think

exact, I use a mac pro and therefore a table monitor, which has a different resolution than that of the macbook pro.
At this point, you should have all the info you need, right?
