programming Iges Import

If I manually do a feature/import data set to iges andbringup options
page then uncheck" Perform full entity check and repair errors"
the iges translates and i get the results I want

Now if I program the translation using
Set model = swApp.LoadFile4(fileName, "i", importData, Err)
the translation happens with the entity check on
where do i set the option for this
