Soliworks API and imported BREP

Hello,

I am developping a plugin for solidworks with the C++/COM API and Ihave a small problem:
I'd like to import a parasolid BREP in the current part (insolidworks : Insert -> functions -> imported geometry).
For the moment, I use the LoadFile2() or LoadFile3() function butwith a parasolid file, it creates a NEW part and then imports theBrep.
It works with an IGES file with the "i" parameter -> LoadFile2("D:\Samples\measuring_cup.IGS", "i") but not with parasolid

Any ideas ? I tried to do a macro in order to see which functionwas called when I import the parasolid file in Solidworks but whenI look at the macro file, it's empty ..SolidworksApi macros
