sharp edges

I need when I run subdivede sharp edges - off, and when SubD of sharp edges - on.

I made composit tool with this toggles, but it works very bad when a couple of objects are on the screen. Is it way to make it work 100% in any cases?

Do you mean Hard_Edges?

Can you post details of the Composite tool you created, it may help me better understand what you are trying to do.
