Annotations you place by dragging cell values from the Data Manager are linked annotations. When you move a P&ID object with a linked annotation, the annotation moves with it. When you change annotation data in the data table, the annotations in the drawing are updated accordingly.
Annotations you add to a drawing using the Data Manager inherit the default AutoCAD text style. You can change the text style of annotations by changing the AutoCAD text style; however you cannot edit annotations with AutoCAD text editing commands.
