Placed illustrator files not to original scale

[individualistic_fan5FDD]

I am placing illustrator files into indesign by clicking, this should keep the image at the original scale correct? But its not, when I check the illustrator at 100% the dimensions are correct, but in the indesign file it is smaller to some weird scale.

I tried opening these .eps and .ai files in Photoshop, and they also come in too large…also at 44.8 mm

Hi @ezariah Can you share the AI file? I’m not seeing a problem when I set Crop to: to Art:

Hi Rob, here you go:

I'm trying to attach the .ai file, but the website is saying "Correct the highlighted errors and try again.

The attachment's position 9 f4_2d orange.ai content type (application/postscript) does not match its file extension and has been removed."

I'm sending the .eps file instead…even though I saved it as Illustrator 2020 .ai before

Looks like InDesign is including the stroke and Illustrator is measuring the outline—the output scale hasn’t changed:

Thanks for the explanation, Rob. I have confirmed this as well.

That being said…I don't quite like the way this is working. Illustrator and InDesign are both running the stroke on the middle of the edge. I was wondering if they were set differently and if that would have caused it…but, no. Anyway, good to know going forward

I don’t use Illustrator enought to know if there is the equivalent of InDesign’s Transform>Dimensions Include Stroke Weight buried somewhere in the preferences, but that’s the difference—the only option InDesign has is to get the placed object’s bounds, which has to include any centered or outside stroke weight.

If I draw an object in InDesign you can see the native object’s  dimensions change depending on that preference:
