About Using Fields in Callout Tools

Fields enhance the documentation capabilities within a drawing file. A field is updatable text that is set up to display data that may change during the life cycle of the drawing. When the field is updated, the latest value of the field is displayed. Usually, you use property set data for this type of updatable information about the building model. However, property set data can be used only in MV-blocks. Fields can be inserted into manual properties in property set definitions, text, MText, attribute definitions and AutoCAD table cells.

There are a number of predefined fields for sheet set information. Most of the fields refer to the current sheet, and should be inserted only in a sheet drawing.

When you are creating a callout tool, you will often use a field from the Sheet Set Placeholder category: These fields let you define a field as a placeholder in a callout for a referenced sheet. The fields are resolved when the callout is referenced into a sheet.
