Kevin, I have used two products succesfully. 1. CAM350 from ACT @ 408-358-4680. They have a viewer called GerberView II. 2. GCCAM from Graphicode @ 206-672-1980. They also have a viewer called GCVue. They both support RS-274-X with support for G36 and G37 polygon fill. They both also run under Windows and Unix. I am curious to know what Design product you use to output X data with G36/G37 and the version number.

What software do you use to view RS-274-X gerber files? Does it support G36/G37 polygon fill? Does it run under UNIX or Windows-Etc? Thank you and have a FANTASTIC day! Kevin L.
