Large Canvas Size issue

[Yeah No]

Hey All,

I'm attemtping to create a graphic in Illustrator that's 665"W x 57"H.

I'll start by creating a new document @ 700" x 700", copying and pasting my art to new doc, scale up said art to 665"w and save.

When I close and reopen the image, it shows a size of 66"w, not 665"w.

It does not seem to keep the large file size.  Any ideeas why this is happening?

Thanks in adavance!

Are you saving the Illustator file down to an earlier version? The large canvas mode is only compatible with AI files saved in 24.2 format and later.

Yup.  That was my probelm.  I was saving it as a CC Eps file.
