Opening prefs...units... and changing from points to inches has no affect. Always reverts back to points. Quit app, relaunch change default to inches, quit app, relaunch...back to points. Change from points to inches, create new document, default is points.

Units refuse to display correctly.

Every time I open my document it defaults to millimetres and I work in pixels.

To remedy this I have to go into preferences, change to another unit type, quit prefs, relaunch prefs, choose pixels (my preference), close prefs. This is the only way I can get my preferred units to display as chosen and it's painful.

I notice below that this issue has persisted through versions with apparent fixes posted by Adobe staff.

It isn't fixed.

The same issue here.

AI 2020 unit preferences STILL don't save / hold / keep active
Mac Mojave & Catalina iMacs 27 in

NEVER will open an mm or cm document in inches. won't create/hold artboards in inches either!!!!!

this is so bizarre since our versions of illustrator 2020 on Mac/mojave & Catalina WILL NOT EVER keep and show unit preferences as INCHES which is what we need on every document we open or create in illustrator.

It NEVER opens a document in inches. what gives?

I am currently using the 2020 version and i would like to have inches as the default unit. It is not available on this version. I had to contact customer support and they only way is keep documents in inches is when i open a new doc and each time i have to change the unit. There should be a way to have all my docs set up as inches under Units. So general and type in inches and stroke in points is what i would like to see.

24.0.2 Unit preference reverts to from inches to points on launching. Must be reset every time.

Changing units doesn't change anything.

Working in pixels but values show millimetres.

This BUG (not an idea) comes and goes with each iteration.

This is meant to be professional software—why are basic things like measurement and colour consistency so useless?!

I am experiencing the exact problem using Illustrator 24.0. It is very annoying to need to reset the increment on every new file

I have exactly the same problem!

Not an idea - It's a BUG -
I change my Preference > Units > General to Inches.
Once I quite and reopen they are Points again.

When changing units from INCHES to i.e. PICAS, units are reverted back to INCHES at next startup - guys... work on this please!

Everytime I start Illustrator, the gerneral units reset from millimeter to points. Is there a way to stop this from happening? Thank you

The most current version of Illustrator auto resets to inches for units with every new document created. I have set preferences for points, quit Illustrator and relaunched to create a new document and preferences default back to inches. This is a bug that needs a fix.

Even though I change the units under preferences to display pixels, if a document was previously setup to display inches, it will not change to display pixels. It just shows inches.
