In general, but perhaps not in this exact situation...
It is often handy and sometimes wise to save the elements to a file, instead of or in addtion to direct copy/paste between differing applications.
For graphics apps, .
PS (PostScript file), .EPS, .AI and .PDF (Acrobat) are the most useful. One can also print to a file (rather than direct to a printer) using a PostScript printer driver and many apps can deal with this file.
