Adobe Illustrator 2015 - Units-Bug

This problem still persists on macOS 10.12.6 with Illustrator 2017.1.0:

Decimal point massive problems (AI CC 2017.1.0 macOS 10.12.6)

There is no Avast software in sight on my MacBook Pro. I’m dismayed how this issue has been ignored by the Illustrator developers for so many years!

Nunca saberão, acabei de descobrir o que fazer.

É ALGO MUITO SIMPLES

CHUPAAAAAAAA MUNDO

Hello, today I've experienced the same problem. Illy 2015.3, Win 10 64bit, Czech Republic setup in Win.

The problem started when I set up my Brother inkjet printer as default in Windows. It got fixed when I set up Adobe PDF as default printer back again. Works ok even if I have comma in "Decimal symbol" in region settings in Win. Anyway, it is a bug...

After hours of searching for a solution, I FINALY FOUND IT. I just installed a previous version of Illustrator and now everything works just fine . here is how to install a previous version :Install a previous version of any Creative Cloud application .

Or just search "how to install previous version of cc apps".

Yes, this issue is still a problem. It’s not just irritating; it makes working with Illustrator difficult and less efficient.

So far as I can tell, Illustrator swaps the decimal symbol with the system digit grouping symbol (or thousand separator). Consequently, the software multiplies numbers automatically as they are entered (not always in the same manner; with comma as decimal and point as grouping symbol, it seems to multiply by ten, i.e., 2,5 become 25, with comma as decimal and space as grouping symbol, it apparently does times one thousand).

With United States regional settings, point as decimal and comma as grouping symbol, the Illustrator app accepts numbers correctly. But of course this is not a solution. Other applications on the same system will call regional settings, e.g., basic spreadsheet tools, and need to work correctly as well in all international versions. (Comments were made about this over a year ago on the Adobe forum…)

This issue did not occur in previous versions of Illustrator and does not occur in other Adobe Creative Cloud applications such as Photoshop and InDesign. – Maybe solutions can be found there.

Also, other CC programs, including Illustrator, handle periods and commas as interchangeable decimal points. Entering 4,5 or 4.5 both result in four and a half. – Which is genius when you’re working in varying regions.

So, is it a system related issue? A preferences/units problem in Illustrator? A decimal or ‘missing decimal point’ problem?

Some additional/optional information below.

Examples

Enter 4.5 as the width in the Transform panel and it turns into 4 5000 cm. Here, unit preferences are set to centimeters, but the issue remains with points or other general units settings.

Trying to take this into account and typing a space instead of a comma, 4 5000 becomes 577 9911 cm. I’m not sure if this is actually five million seven hundred seventy-nine thousand nine hundred eleven centimeters (thousands divider in wrong place), i.e., 5 779 911, or five hundred seventy-seven and nine thousand eleven one ten thousandth of a centimeter, i.e., 577,9911 or 577.9911 (comma decimal or point decimal respectively). Either way it’s much beyond my artboard in Illustrator all of a sudden.

Well, maybe there’s no need to compensate and substitute decimal symbols. However, if I enter 4.5 as I did first, and click on the object to continue working or press tab and continue, my 4 5000 cm becomes 577 9911 cm again. Depending on proportion constrain setting, both width and height or first height, but eventually both will change to that value.

General Preferences also displays value in a strange way… 45 7200 cm as Keyboard Increment… 0 00°… 0 42 cm. Basically, any number in Illustrator is afflicted.

System and application settings information

I am using the English language version of Illustrator in a US English Windows OS (details below). My numbers format customization in Windows is, however, set to comma as decimal symbol and space for digit grouping. My location is set to Belgium.

The problem is not document specific; decimal points or commas keep vanishing in new documents, whether I restart the software or both software and the whole system or not.

I have also uninstalled and re-installed Illustrator, however I did, so far, keep preferences, and have not tried re-installing the entire Creative Cloud suite.

System information: 64-bit Windows 10 Pro version 1511 operating system, Build 10586.494, running on a Dell XPS 8500 Intel® Core™ i7-3770 x64-based processor, CPU @ 3.40GHz, with 16 GB RAM installed (info file available).

Software information: Adobe Illustrator CC 2015.3.0 Release 20.0.0 (64-bit); no further updates available at this time.

After updating my Windows 10 to WIN10 Home version 1607 got same problem few days ago! Not solved yet! HELP! At this time I have Illustrator CC 2015.3.0 Release 64bit.

I still have this problem in Illustrator CC 2015.3.0 (20.0.0) 64-bit. Not in other CC products.

I have this problem too, but if i just input using decimal point instead of comma (like "1.0"), the stroke input box still says a way off value like "1 000" pt but the stroke itself is correct.

Seriously? Changing system wide settings to work around a bug in one or two apps? This is by far the worst advice I have ever seen.

Earlier this year I was thinking of moving to Serif or Corel, now might be a good time to take the plunge...

Take your responsibility and fix this now!
