Need help in linking attribute to symbol in NX

Hello All,

I need a small help regarding linking a teamcenter attribute to an NX custom symbol in drafting application.

I have an attribute in teamcenter which is  mapped to the NX attribute . I have a symbol stored in the custom symbol library. Further I want to link this attribute to this symbol in NX. The symbol should be controlled based upon the  the attribute value from the teamcenter.

I was trying to link this attribute to the symbol using expressions. Can you please help me which is the best way of linking the attribute. Thanks in advance.
