Which tool maintains shared polygon boundaries when modifying neighboring polygons in map topology?

The Reshape Feature Tool is designed to modify the shape of existing polygons while preserving the shared boundaries between neighboring polygons in a map topology. This capability is crucial in maintaining geometric integrity and ensuring that when one polygon is altered, adjacent polygons remain accurately represented without duplicating or losing their shared edges.

When using this tool, users have the ability to adjust vertices of a polygon and make necessary modifications while keeping the connectivity intact with adjoining features. This is especially important in situations where precise spatial relationships are necessary, such as in land use planning or environmental management, where multiple features may interact with each other.

The other tools listed serve different purposes. For instance, the Reshape Edge Tool is focused on adjusting a specific edge of a feature rather than maintaining integrity with neighboring polygons. The Trance tool is primarily for moving features without altering their shape, and the Split Tool is used to divide a polygon into two or more parts, which can disrupt shared boundaries rather than maintain them.
