计算要素的长度并将其添加为新属性。
Using this transformer on a polygon will produce the polygon's perimeter.
To calculate the partial length of a feature, use theLeaderTopOintCalculator..
要计算从行开始到每个顶点的距离，请使用MeSuctGenerator..
Parameters
长度尺寸
By default, the two-dimensional length of the line is calculated, and any Z values, if present, are ignored.
为了计算3D长度，长度尺寸参数应设置为3，然后升高将包括在长度计算中。
Multiplier
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.
Length Attribute
Name of the attribute to hold the length value that is calculated.
