Cad Drawing Viewer

For my CAD class in school we are trying to make a portfolio for university / field work. But to do this, we will put all files on a disk. Is there a viewer that supports drawing Inventor, Revit and AutoCAD can also be placed on the disc then when you go to a PC, all you need to read a file is just in front of you?

None that support all the programs I know, especially Revit. I think that Autodesk has bought and is selling it, not as compatible with other products that the CAO. If you just need to show leaves to try to save the PDF in this way, they can be accessed from a program. There are many free PDF creators online. Hope that helps some. Good luck.
