autocad stamp problem

[ieu]

Hello I would have a problem:case 1) a program gives me a dxf file in which there are beams in scale 1:50 and of the sections of this ultratime next to scale 1:25; a width that in reality is 30cm on the model gives me 60 units; for the section instead the side 30 cm me from 120x.After having saved it in dwg to be able to work on it, I prepare my sheet for example a4 and then I go into the layout,imposed by management settings page the characteristics printer (or pdf creator or from dwg to pdf) leaving scale 1 to 1 .creo the window,
the version is autocad 2020 for students .I ask you :1)from what depends this error?2)because beams and section are flanked but in different scales,to keep the respective stairs I have to make a window for each or there is a system for having them in a single window and keeping the stairs?

autocad printing works like this:
unit x print scale (mm/unit) = printed mm.
banal example: 60 units x 1mm/unit = 60mm printing; 60 unitsx 0.1mm/unit = printing of 6mm.

this always applies, even when working in the layout.
a second scale intervenes in the layout, which is the window scale compared to the model.
if you frame with a window whose scale rapp. is 1:1 model, your 60 model units remain 60 units even in the layout.
but if the window has scale 0.5:1 then in the layout your pattern units become 30 and the print will produce 1:1 will produce 30mm printed (on that window). next to this you can have a window scale 0.1:1 and look at your model (even the same piece of first), climbed 5 times smaller.
what you need to check well is the scale of the window, because when you create a new layout, autocad adapts all the model to the available area (by changing the scale ratio of the window), but above all, if you enter the window (double click in the window), the zoom is equivalent to a change of scale window. all zoom and pan operations must be done in paper space, to avoid changing the window scale.
the way to avoid such thing is to block the scale of the layout window (when in paper space select a window, on the bottom bar next to its ratio you scale you will see a padlock you will block).
30 in scale 1:50 should be 6mm (not 0,6), and 300 should be 60mm.
but are you so sure that (printed) you measured 6mm and not 5,8mm? Can you distinguish printed 2/10 mm? even the natural deburring of ink allows you to evaluate with certainty 2/10mm printed. . .
probably it's 5.8mm (and you've evaluated 6), while for the 60mm window scale scrap multiplied by 10 allowed you to appreciate it correctly.
or is a printer calibration error (a rare event). try printing the model with the same printer and check what happens.

print of a carpentry in plant 1 to 50, reference elements 30x30 cm and distance between the consecutive pillar centers (interassee pairs to 3m), in scale on the sheet must be: plate 0,3m/50 = 0.006 x 100= 0,6 cm, interassesss 3m/50 = 0.06 x 100= 6 cm.in the program chooses print scale 1:50 , press scale 1mm=5 unit with scale drawing 1:50 will be obtained that in cad 1m will measure 100 units.). 1xf.2)pro autocad 2020 version students and except dxf in dwg.3) I open the dwg, the pillar side measures 60 and the interrasse 600 units; in the layout I go in management setting page -modification-imposed printer pdf creator, 4 scale 1mm= 1unit.3)in the space paper genero window and I click in to center imagepdf

I'm sorry if my question is stupid, but reading your post has come to me migraine.

I read that at the end of your entire process generate a pdf and then print it, and by measuring the pdf "with the ruler" do not return the measurements, so I ask: Are you sure that when you print pdf you didn't flag a "suitable" item, which distorts your pdf to the actual print area of your printer?

because the 0.6cm that melts as a pillar side perhaps in reality is 0.58cm but with the ruler you struggle to evaluate it, while the 5,8cm of course is a macroscopic and obvious error... .

I wonder, eh...

@place hai risolto

I keep saying the same thing.
I wonder how a person can measure on paper 0.6cm instead of 0.58cm.
even the measuring notch on the ruler I think is wider than 2/10 mm.
But don't you mix with a caliber? ?

then I agree with spider... migraine is assured to read that post.

another point not clear is why switch from pdf to print. autocad doesn't print anymore?
acrobat is set by default to print in suitable size, so nothing easier than the pdf is correct, but the output on pdf paper is adapted to the print area.

second thing uses dwg to pdf as a printer and not pdf creator. much more flexible, you can get to formats that the creator doesn't even dream of.

autocad print directly on printer, and check. all the rest of it then.

@cristallo I think we can tell each other...

I should like to thank the rapporteur for his work. .

I find the same problem with autocad 2023 for students.
if mold directly from the 1:1 scale layout the lengths are preserved.
if I create pdf and then mold the design the lengths become smaller (10cm turn into 9.6cm).
You got it?

if I have to send 100 copies in copy shop I must pass by pdf force that reduces my lengths (100mm become 96mm). no need to use the caliber.

with which mold format? Do you consider the printer's margins?
a format (paper) a4 cannot contain a rectangle 21x29,7, each printer has a blank margin around the page.
when you print from pdf, adobe is set by default to let you enter an a4 (paper) on a suitable a4 printer; and that margin of 5mm around the page is recovered by tightening the page. set "effective size" when you print.
but you don't print it, so how the soft print is set you don't know...
sending to print a pdf in copisteria as you do, steps from:
scale model-> scale layout, scale layout->pdf, pdf-> paper (not performed by you). in which of the 3 passages is the error born?
pattern printing on your local printer a 10x10 square and see if with the measurements you find us. If yes, then the error arises in the other steps.
local print a 10x10 from layout, if the result is correct... You can tell the copisteria "cane you gave me 100 high-end copies, refractives"

I agree with you @cristallo print at your home and check the size. Are you okay? go back to the copisteria and reprint them for free and just

in pdf printing settings instead of saying fit, put 100% custom scale. .
to me was this problem
Maybe so solve
