Dissolves solid features by removing common boundaries to create larger solids. Input attributes may be accumulated.

How does it work?

The SolidDissolver accepts solid features and removes common boundaries, creating larger solids where possible.

Aggregate input may be deaggregated or rejected by the transformer. If deaggregated, attributes on the aggregate feature will be propagated to its parts.

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

Dissolved solids are formed when shared faces and interior boundaries between intersecting solids 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, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
