Catia CATScript doesn't create a geometry!!!!???

I use Catia V5 to create my geometry. I maked a macro.CATScript in which I would like to change the parameters of some surface. At the end the macro makes a Update and then saves the geometry to STL file. So i think that all the things goes right but when I verified I found that the Geometry was the same of that of the beginning (unchanged geometry). Anyone can tell me why???

bye thanks

I'm not sure about problem Whenever I had experienced the error, I used "cln" commands to origin cad file to check geometry
