Adobe Illustrator: Shape and Transform measurements always change automatically to something random

[robertk26996964]

Hi,

I'm having this issue since the last 2 CC updates and haven't found solution anywhere online for it.

Basically any time I make a shape for example 512 x 512mm square when I click enter the size of the shape keeps changing to something random like 513.024 x  513.024mm (sometimes second number can be different and not even the same). I suspect its something to do with rounding it to the closest pixel size etc, but its causing a lot of issues for me for projects that I need exact millimeter size for print/fabrication files.

When I go back into Shape height and width even if I try and change it back to 512mm repeatedly it still shifts measurements to different number and only rarely do I get it to stay at size I told the shape to be at. 

Anyone had similar problem and got a solution how to fix this in latest Illustrator CC version?

Is the 'Use preview bounds' option checked in the Align panel menu?

Hi Doug yes its checked.

Then uncheck it, because it causes this.

Usually it happens when user seamlessly align your artwork with the pixel grid...Can you chek your settings for these options Seamlessly align your artwork with the pixel grid...

The issue has been solved already. It was "Use Preview bounds".

I have the very same issue. Found this thread and tried to uncheck the 'Use preview bounds' option, but still got the same error.

Can you show your object selected and the transform panel?

Same here - I have align to pixel grid switched off, I have the magnet thing switched off, preview bounds is off, align to pixel everywhere I could find it switched off and it STILL keeps changing it to a random number which is driving absolutely mental! I swear every time I update illustrator it just gets incrementally more of a pain in the ass to do basic stuff.
