Something that's baffled me for years; is why Illustrator cannot maintain layer structures when opening PDFs that are compatible with it. I work extensively in Esko ArtPro+, who's native file format is PDF.
We are constantly requested to supply file back to Designers in a format that is Illustrator compatible, and this would be seemless if the PDFs maintained the layer structure.
The files maintain their layer structure when opened in Acrobat Pro, but as soon as they are opened in Illustrator the file only contains 1 layer with everthing on it.
Does anybody have any thoughts or workarounds?
