Light Fixture, HVAC, Ceiling line weights?

[m_cahoon14336]

I have a 2x2 suspended ceiling with standard revit library lay-in light fixtures, hvac diffusers, etc. I am trying to make the fixtures and diffusers print darker. I have changed the line weights via object styles, but this does not seam to change it for me. How should I go about making this change?
Thanks

That should do it, open the families and see what object style the symbol lines are on. Then make sure that is set to the lineweight you want

Thanks Scott. It was a dumb error on my part. It works as it should now.
