Use these settings for relaxing vertices in Interactive Manipulation mode. Relax in Edit/Editable Poly works much like the Relax modifier: It normalizes the distance between each affected vertex and its neighbors by moving the vertex toward the average position of its neighbors.

AmountControls how far a vertex moves for each iteration. The value specifies a percentage of the distance from the original location of a vertex to the average location of its neighbors. Range=-1.0 to 1.0. Default=0.5.
IterationsSets how many times to repeat the Relax process. For each iteration, average locations are recalculated and the Relax Value is reapplied to every vertex. Default=1.
Hold Boundary PointsControls whether vertices at the edges of open meshes are moved. Default=on.
When on, boundary vertices do not move while the rest of the object is relaxed. This option is particularly useful when working with multiple elements within a single object that share open edges.
When this checkbox is off, all vertices of the object are relaxed.
Hold Outer PointsWhen on, preserves the original positions of vertices farthest away from the object center.
