Hello
Thanks for your help. For the last question it seems that informations which are shown after using "Add/Move HVAC Label" are not connected only with Annotation_DG.cel. In my case for example "Round Duct" has marked two informations: End1/diameter and center of gravity but when I use "Add/Move HVAC Label" I can see only diameter. As I checked information from Annotation.DG are shown after using "Place DataGroup Annotation" tool for sure.
What is more in Annotation_DG.cel for "Round Duct" or "Rectangular Duct" I can't even choose top of duct information because it isn't on a list:/
