Calculates the length of a feature and adds it as a new attribute.
Using this transformer on a polygon will produce the polygon's perimeter.
To calculate the partial length of a feature, use the LengthToPointCalculator.
To calculate the distance from the start of the line to each vertex, use the MeasureGenerator.
By default, the two-dimensional length of the line is calculated, and any Z values, if present, are ignored.
To have a 3D length calculated, the length dimension parameter should be set to 3, and then the elevations will be included in the length computation.
The multiplier parameter can be used to scale the length from being measured in ground units (the units of the feature's coordinates) to something else.
Name of the attribute to hold the length value that is calculated.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
