dear community

I am trying to get flattened model of a sheet metal part through API program(with the below code). but not getting results. the bent state of the part is not getting changed. have ensured these models are recreated in the Solidworks sheet metal module only.

//select bodyfeature to get flatten model 
 

bool selectBody = swModelDoc.Extension.SelectByID2("Flat-Pattern", "BODYFEATURE", 0, 0,
