Thank you all for your work. How could I have the areas in square meters (m2) unit?
Thank you all for your work. How could I have the areas in square meters (m2) unit?
That's quite easy, just divide the area in cm2 by 10000. I have updated the script so it will display also in m2.

Thanks for the fast reply and update!
I'm having a little issue and I don't know why and how to fix it: I draw a 100cm x 100cm square, run the script and it shows "0,010m2" whereas it should display 1m2.
On another AI document it works perfectly: I draw a 100cm x 100cm square, run the script and it shows "1.000m2"
Do you have an idea about what/where is the problem?
Thank you.
Or if you could attach the problematic file, I could check it for you.

Can't attach an AI file unfortunately, and can't also put a WeTransfer link.
do you have screenshot? and could I see the document settings, I think there's a corner case that I haven't covered with this script.
…
Weirdly I can't reproduce the bug. It would be better if I could have the file though.

I'll send you by email.
ok that would be great

I've made an altered version of this script,allows you to pick units and also set accuracy. There are updated versions of this script actually
In my repo i added 2 version, im sort of still working on v5. That ones has some dev comments in them. I added more options like unit comparison and some others and also a complete dialog panel. I think the base code was from that gist of Bryan Buchanary and some additions from a different user. That person added a method to work with cutout shapes. Though that does not work when there are multiple cutouts. At least not properly
I cant find that other gist at the moment, these gists are a bit weird. When you quote it doesnt add the name, so response are hard to track. I always try to manually @ them using @and then the name. Im also trying to find the gist where all that other work was done. Some others have contributed really good to that code.

Edit
ive found the gist again, it was from here; https://gist.github.com/bryanbuchanan/11387501

Hey, I've looked into the file. And yes, I see the problem. And no, I don't have any clue why that's happen XD... One thing that I notice is that all the unit is weird. For example, in that file, when you create new Artboard, and set it to A4, it shows 2100mm x 2970mm, the normal one is 210mm x 297mm. Somehow all the unit is displayed 10 times than it actually is.
I'm curious, how could you make this file?

Nice :D... I haven't tried if your script will work correctly with this case. @rivieraneon should try it.

First it says "FALSE" in a first window, and then "100cm2" so same problem as it should say 10000cm2
ok that would be great

I have an official AI licence, I made this file by doing CMD+N (make a new document) and that's it.
First it says "FALSE" in a first window, and then "100cm2" so same problem as it should say 10000cm2
As @alijaya noted, your file is not correct! I tried it myself and make a cube of 100 100cm and get returned 1000cm2
Could you share that corrupt file, idd like to have a look at it?
I what illustrator version has that file been created?

I'd need an email as I can't upload the file here.
Illustrator 2022 (26.0).

Ive found the "issue", its because your document has the documents raster effects resolution set to 35ppi. This script should set that temporarily to 72 dpi since that is the measurements it uses.You can find this in Effects > Document Raster Effect Settings > PPI
I think it could be added to the script to temporarily set this to 72dpi than when done revert to old settings.
EDIT
Nevermind, just check it again and it showed 0.01 again, not sure whats wrong with this document now?!
I check the code and its hardcoded to use 72ppi
PS i did noticed something else. I had an idea of saving your file to a new file and reopening it. When i did so, i noticed the square now suddenly was 100x100mm?!? There really is something odd with this document.
Finally I found what's wrong with this document hahahaha... Basically it has something to do witht the feature of Illustrator, namely Large Scale Canvas. https://helpx.adobe.com/illustrator/using/large-sized-artwork.html
Basically if you create more than 227in (5.77m) artboard, it will use the setting of Large Scale Canvas, basically that's why it happens. So I need to find how to get this information from scripting, and doing simple if.
@rivieraneon I have fixed it. Could you try the new script?
I have found solution here https://community.adobe.com/t5/illustrator-discussions/get-true-artboard-size-with-quot-large-canvas-quot-document-from-extendscript/td-p/11216761
Basically we could get the scaleFactor of the document, so I use that value to correct the size. It should work now.
Thanks now it's working even on the weird/wrong document I sent you both!
Many thanks to you 2 for your kind help and efficiency!
Glad it's finally working :D
Haha that is funny, i was actually looking at that feature after reading this very long thread on adobe community. What a coincidence!!!
Never thought it would be linked to that setting!
I do wonder now,why was this document read a being large scale? Was this document first setup like that and then later scaled down?
I think this could be added in the code. Apperently what adobe does is scale it in the background. That is there trick to get these huge documents working
You could try this code and see if semething related to large scale is in the attributes. I use these simple loops to find all items available through code.
items = []
for (attr in app.activeDocument){
items.push(attr+", ")
}
alert(items)
Then you can alter the for loop if you a attribute you think is connected, then run it again pointing to that attribute
After checking, my earlier script did not get very far. Ive found this great read on StackExhange, it references the scripting reference PDF and the Illustrator settings file, probably it show the correct name for the scaling to get the value for scripting.
I think im gonna check tonight at home and dig through that preferences file see if i can find anything related. Though i would guess such a setting would be saved as a setting in the document. Ill chech that as well
Nice work @alijaya i was thinking about something similar. But you code is much cleaner than my approach would have been ..
