<_param name="measurehelp" type="description" xml:space="preserve">This effect measures the length, area, or center-of-mass of the selected paths. 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%.</_param>
