Unacurate vector image sizes in Illustrator

[Luc St-Pierre]

I have a huge blank.... please help me. This thing never happened to me. In Illustrator when you trace a vector shape using measures, why would they suddenly be rounded to some funny numbers. Example, you order a rectangle of 8 x 10 and it comes out as 7.9997 x 10.00023 ???
I am stunned, or I begin an Alzheimer condition . . .
Thank you

Can you be more specific on what you're trying to do? Just drawing a box, or tracing an existing element? Are your Illustrator [preferences] and document [document setup] Units both set to the same thing - inches, millimeters, etc?

 

[Lukas Engqvist]

Are you using Adobe points or traditional points? I would assume using Traditional points could give you complicated maths.

I've noticed this to, and don't how or why it happens.
Agrevating for sure...

 

[Luc St-Pierre]

Both my document set-up and units preference are set at “inches”. I hit the square box, key in 10 x 10 and the box is really 10.0139 x 10.0139 . . . annoying !

Do you have a stroke applied to your box when it is drawn? Try looking at the measurements without a stroke applied.

 

[Lukas Engqvist]

It seems more to be the way the measure tool jumps. I suspect the grid settings to be giving you the problems.

We are close to a solution. Yes, indeed without strokes the values are dead-on. Is there a way to make Illustrator ignore stroke value?
Thank you

depends on where you have the stroke set to originate, inside, outside or split. It gives you the full outer most dim.

doesn't this also happen in InD CS3?
Draw a 3.5 x 2 box and it measures 3.5035 x 2.035.

In your preferences, make sure "Use preview bounds" is deselected. This should take care of it.

That was it !!!! Alleluia !!! Thank you so much.
