Reduce Collapse Tools

Use the Reduce Collapse and Reduce Collapse Selection tools to collapse selected polygons and merge the surrounding vertices together. They remove the selected polygon without destroying the integrity of the geometry. Selected polygons are deleted but no hole is left behind. The gap is closed by merging the neighboring polygons together.

• Reduce Collapse - Selected polygon faces collapse and the surrounding vertices are merged together.

Before	After

• Reduce Collapse Selection - Selected polygons split into six polygons and merge together at the center.
