thanks, that's what I thought but I'm new to cadworx so I had to ask. I have been using generic nozzles, just didn't know if that was proper. My last 3d project was using autocad plant3d. In it you can highlight a group of solids and give it a equip number, then add nozzle info that recognizes the equip on isos. thanks again for the help, I'm sure I'm going to need more.
