Problem on savenig STP file in CATIA V5

I found a surface with IGS format, and I convert it to a Solid model using "Close Surface" command (in Part Design). Finally I save it as STP file, but when I open the STP file in CATIA, it appear as surfaces and there is no Solid Model (like saving a model in IGS format, see pictures).
why this Problem occur and what is the solution?
Regards.

Hi,
copy the solid and paste it "as result" in a new part.(no reference for this solid still exists) Then save this part as STP file.

STEP FILE FORMAT CONVERSION ALWAYS CAUSE MORE TROUBLES,
X_B OR X_T FORMAT ARE MORE RELIABLE AND PRECISE.

There should not be any problem.
You can select .stp format while saving.
Could you give some more details about your problem?
