The flexibility of the new UI is awesome. I've created a partial customization file and set up the ribbon tabs and panels with our custom schedules, legends, etc. etc. They work perfect. I copied the Autodesk supplied panel "Annotation HVAC" to my customization file. This panel is a combination of Autocad annotation commands and MEP annotation commands. The entire panel structure copied over as expected. The problem is only the Autocad based icons made the trip. All the MEP icons have been lost and replaced with ?. Is there a way to fix this?
