Hi Lawrence,

for our Simulator we need to extract the smc-values of a flt-File, too.
I have no problem with the Extraction.
Perhaps you miss to init your flt-Loader by calling : pfdInitConverter
("dummy.flt").
As i want to extract from every node, i use the ConverterMode :
pfdConverterMode_flt( PFFLT_SORT_FEATURE, FLT_FTR_ALL )
After these init-Calls I can get the SMC-Value by calling :
 - fltFeature *userdata1 = (fltFeature *) gstate->getUserData(
pfdGetConverterMode_flt( PFFLT_USERDATA_SLOT ) );
 - int smc = fltGetFtrSMC (userdata1);

hope this helps,

Marc
