How can I do it? I have tried iso-surface,but it create surface like B to B surface.Cuting plane or split surface in Geometry also no use. I know that it can easily do it in Fluent,but I can't relize it in CFview

All the 3D views (cartesian, cylindrical and STM) are linked. If you create a surface in any of them, it will be available in the others. In your case, you can create a surface in any of the view and use the split surface (Geometry/Split surface...) in the cylindrical view for extracting an annular surface as you can see below:

This gives the following in the 3D view:

The grey surface is the original cut and the red one is the annular section extracted from the cut. Does it correspond to what you are looking for? Thank you.
Best regards,
Alban

Thanks a lot.It's really useful. And I never see this link between them before.
