error 2128 revolving a geometry

Hi everyone.
I'm using comsol 3.5a in Windows 7 64 bits. When I try to revolve (or extrude) a geometry (or mesh) in an axysimetric mode I get the error 2128 "Unsupported operation on this type of manifold". Saddly I couldn't find any error guide that may help me to solve my problem.

Here is a screen capture:
