抹布

通过去除共同的边界来溶解区域特征以创建更大的区域。可以累积输入属性。

Input Ports

  • 该变压器接受二维多边形特征,包括甜甜圈。这些多边形特征广泛称为多边形。
  • 聚合输入将由变压器进行分析。聚合功能上的属性将传播到其部件。

Tip: If part-specific attributes, such as areas, need to be computed and preserved, pleasedeaggregate在溶解之前。

Because aggregates are deaggregated inside the Dissolver, it is possible that the number of output features will exceed the number of input features.

  • Dissolved polygons are formed when shared edges and interior edges between adjacent polygons are removed.

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, clickbeside the applicable parameter.
