Datum Feature SymbolDatum Feature SymbolA datum feature symbol consists of a marker, leader, and datum reference letter.
To insert a datum feature symbol:
Click the Datum Feature Symbol tool from the Dims/Notes tool set.
Multiple annotation tools share the same position on the tool set in some workspaces. Click and hold the mouse on the visible tool to open the Pop-out Tools list and select the desired tool.
Click to place the object in the drawing, and click again to set the rotation.
The first time you use the tool in a file, a properties dialog box opens. Set the default properties, and click OK. The properties can be edited from the Object Info palette.
To add a shoulder to the leader line, click the Selection tool from the Basic palette and drag the control points on the object. Edit the marker from the Attributes palette (see Marker Attributes).
The datum reference letter (which corresponds to the Feature Control Frame reference letter) automatically increments each time you insert a symbol.
To control the text characteristics (font size and style) globally, assign a text style to the class. You can also apply text styles or Text menu options to format individual markers. See Using Text Styles and Formatting Text.
