Orcad has a Gerber viewer, and a 3D viewer (used to called Intellicad, but
believe it has changed its product name). I believe they are both
unsupported products, and the 3D viewer requires export to a different file
format (one of the AutoCAD ones IIRC) and requires one to be using the
Capture CIS version so you have component height information in the
database.
