Length and area are added as a text object with the selected units. Center-of-mass is shown as a cross symbol. * Text 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. * When calculating area, the result should be precise for polygons and Bezier curves. If a circle is used, the area may be too high by as much as 0.03%. path
