Which transformer dissolves boundaries between features that share an attribute?

• A. Dissolver
• B. Clipper
• C. LineBuilder
• D. AreaBuilder

Answer: (A)

Dissolving boundaries by attribute means merging adjacent features that share the same attribute value into larger features, removing the internal boundaries between them. The Dissolver is the transformer that does this: it groups input features by a chosen attribute and dissolves the shared boundaries within each group, producing fewer, larger polygons or multi-part geometries for each distinct attribute value. For example, if you have parcels with an “Region” attribute, dissolving by Region will merge all parcels in the same region into one feature, with the boundaries between them removed. Other transformers mentioned serve different purposes—Clipper trims features using another feature, while LineBuilder and AreaBuilder construct geometry rather than dissolving existing boundaries.
