+  * Display format can be either Text-On-Path, or stand-alone text at a specified angle.
   * The number of significant digits can be controlled by the Precision field.
   * The Offset field controls the distance from the text to the path.
   * The Scale factor can be used to make measurements in scaled drawings. For example, if 1 cm in the drawing equals 2.5 m in the real world, Scale must be set to 250.
