How to export Trumpf Geo file from sheet metal part when it contains a SB-Louver.

Couldn't export Trumpf Geo file from sheet metal part when it contains a louver. (Louver produces invalid loop in Trumpf GEO)

Users need to turn off File->Preferences->Sheet Metal->Flat Pattern Treatments->Show Louver Cutout Curves as Interior cutout.

This will mark louver curves as interior feature curve. Issue is fixed NX2206 onwards. After changing the preference user needs to create new Flat Pattern or renew existing Flat Pattern to get the fix.
