Additional Symbol libraries in NX

Hello everyone,

This is my first post in this forum. I need help with additional symbol libraries in NX. I was asked to come up with instrumentation system diagrams and flow diagrams with industry standard symbols, and currently my only tool to work on this is NX. I was trying to do all the work in the Drafting module, but I do not see any industry standard symbols for either instrumentation or flow (valves, actuators, solenoids, etc.) Has anyone had experience with this? If not on NX, do you suggest another CAD software.

Thanks.

Rodrigo
