Operations [Select] Type of unification operation to perform.
Remove Coincident Faces [Compound] Removes faces that may be connecting the same vertices.
Unify Planar Faces [Compound] Unifies faces that lie on the same plane. Vertices should be shared, so applying a vertex unification first may be necessary.
Unify Vertices [Compound] Merges mesh vertices that are overlapping (or positioned close together) into the same vertex reference.
Tolerance [Float] The distance tolerance used for determining if two vertices should be joined.
