CADWorx HVAC tab: HVAC Database > Synchronize 
Command line: HSYNC
Checks all components in the drawing and updates them according to the current value in the database. This command does not write new records to the database for new components that are in the model but are not in the database.
When a drawing has a live database attached, you can open the database and edit the SHORT_ANNOTATION, LONG_ANNOTATION, DESCRIPTION, PART_NUMBER, and MATERIAL fields in the HVAC table. Changing any other column value does not have any effect on the drawing.
