PathBuilder

每当一个时，正在创建的功能Connection Break Attributevalue changes. When this happens, the feature with the differing attribute is not added to the current output feature; instead, it begins the next feature to be output.

If consecutive input segments are lines, they will not be combined into a single line in the output path; they will remain as separate segments. Also, if only one segment is input for a set of Connection Break Attribute values, the output will still be a path (containing that single segment).

如果提供，列表是在创建输出路径时连接的每个功能的所有属性。

笔记：列表属性从工作台中的输出架构无法访问，除非首先使用在它们上操作的变压器处理它们，例如list exploder.或者ListConcatenator. All list attribute transformers are displayed in the Contents pane of the Transformer Help under清单. Alternatively,attributeexposer.can be used.

当在2D中查看（忽略z）时，路径（可以定义多边形的边框）可能看起来是关闭的，如下图所示。在3D中查看时，该路径可能看起来可以打开，如下图所示。

要指定如何（和if）路径应在3D中关闭，选择其中一个列出的模式。

模式	描述	Example
延长	曲线延伸，使所有顶点留在原始位置。
Average	Subsequent vertices that are not connected, but share an x and a y value are combined into one vertex, whose Z value is the average of the original two.
第一次获胜	未连接的后续顶点，但共享x和y值组合成一个顶点，其z值从第一个遇到的顶点取出。
Last Wins	Subsequent vertices that are not connected, but share an x and a y value are combined into one vertex, whose Z value is taken from the last encountered vertex.
忽略	z值忽略。没有更改节点连接的方式。
