I try it with Solidworks 2012 now it's working
I think this problem is about lighting
Goto the properties of the applied material (glass) and set the transparancy at 95-100%.. Do let the preview fool you....glassy materials do not show properly @ preview, the final render will be much better...
I set transparency to 0.98 and change some setting but its not so transparent.

Have you tried increasing your final render render quality? The "good" (lowest) setting only allows 4 refractions.
Check if In Photoview 360 Options, you have "Custom Render Settings" checked, maybe sometime earlier you were messing around with these options, just uncheck it, and it should render well in both the preview and final render, without the quality being a factor
thanks for the information
