Topods_shell

I try to make a topods_shell with some topods_face but it doesn't work.

In the Open cascade help, I read that the constructor of this type of shape use a geom_surface, so I tried to make a geom_surface with my topods_shape and a TopLoc_Location But when I tried to compute, I had an error on my shell!

--------------------------------------------
.....

TopoDS_Face F4 = BRepBuilderAPI_MakeFace(W4);

TopLoc_Location location;

Handle (Geom_Surface) F11=BRep_Tool::Surface(F4,location);

TopoDS_Shell shell1= BRepBuilderAPI_MakeShell (F11);
.....
--------------------------------------------

After that, I tried with this syntax because there is a second constructor witch use a geom_surface and four real, but I don't know what are their utilities:

---------------------------------------------.....
TopoDS_Shell shell1= BRepBuilderAPI_MakeShell (F11,10,10,10,10);
.....
---------------------------------------------

I had no error but when I tried to display my shell in the viewer...there is nothing.

I'm afraid this problem isn't difficult but I don't find the solution alone. So if you have a simple example for me or an explication...

Thanks for your help.
