Where you're talking about Acrobat 3D, I'm going to assume that you want to be able to manipulate the decal in a 3D PDF. If this is the case then you'll want to open Acrobat and bring the decal in as a part. Acrobat will walk you through the necessary steps. My computer is hosed, so I can't do it right now.

I think Jeff is right. You can save as a 3D PDF from SolidWorks, but it looks like you need Acrobat 3D to add a decal. Are you using PhotoWorks decals?
