I believe you are talking about a "tech-pack". They are essentially everything you can compile for the product. Patterns, colors, fabric swatches, stitching, logos, etc.
Im in the process of having a wallet I designed made (not a piece of clothing but still needs to be sewn), and I just made the pattern as a solidworks drawing, then saved as a PDF so it is more universally readable.
I don't work in the fashion industry, so I'm not sure if there is any special program (I also couldn't find one that did anything special when I researched). Plus as along as I had the pattern and everything included, it didn't seem to matter.
That said, there is a company in AZ that does this kind of stuff for you (http://www.protosew.com
). Maybe see what they can do for you.
