Combining multiple Illustrator files into one PDF
For my work I use a combination of Photoshop, Illustrator, Visio, Excel and other things to make pictures and diagrams. I then want to combine them into one large PDF. Combining multiple files to PDF in Acrobat Pro works for the non-Photoshop/Illustrator filetypes, but for whatever reason doesn't work with AI or PS.
Is there a way to take advantage of this useful tool to work on Adobe's own products (the supported formats does not list .ai or .psd)? Going through and exporting each to PDF can be tedious.
If you have access to InDesign I think that your best option is to place all of your files in one InDesign file and then export your InDesign file as one PDF file. This really simplifies your process especially if you're going to be updating the original .AI or .PSD files at any time. You may even be able to place your other non Adobe files into the InDesign file in their original file type or as PDFs. This can even help you with your pagination and page order.
