I am 95% sure that FTView View ME 6.0 lets you create a 3.0 file
50% sure that FTView ME 7.0 lets you create a 3.0 file
FTView 8.0 and newer definitely will NOT create 3.0 file.
And just as a side note, Rockwell seems to have dropped the existence of version 3.0
It was not a good release. If your PanelView runs fine on 3.0, okay. But if you have any issues at all, then I highly encourage an upgrade to 3.2 (which then also lets you use the newer FTView Studio to build those files).
