I started from one of the out-of-the-box templates for MEP 2008, and I've been editing it to our company standards (layers, colors, etc).
Suddenly I've discovered that when I insert an Air Terminal Tag, they come in on layer 0. I'm trying to figure out what got changed, and how to fix it, but I haven't found anything anwhere about how to tell MEP what layer a tag should go to.
Duct sizes still go to the correct layer, so the problem is specific to terminal tags, and not a general, total screw-up.
Has anyone figured this one out? I've been through the Style Manager and the Tag Properties and Property Data Sets and everything I can think of.
