Smooth

The Smooth command averages the positions of object points or vertices. This command is useful for removing unwanted detail, and for removing loops in objects.

When mesh vertices are selected, you may have to use the WeldVertices command before smoothing in order to prevent the mesh from pulling apart.

Smooth Options

Smooth X / Y / Z

Smooths only in the specified x, y, or z direction.

Fix Boundaries

Prevents naked edges or endpoints from being moved.

Meshes: Vertices along naked edges will not be modified.

Curves: End control points will not be modified.

Surfaces: The control points along the boundaries of the surface will not be modified. The edges and trims of trimmed surfaces will be modified if they do not coincide with the surface boundary.

Note

• If all of the object points are selected, Rhino perceives this as the whole object being selected.
• Fix Boundaries may cause undesirable seams or singularities in closed curves and surfaces.

World / CPlane / Object coordinates

Use world or construction plane or object u, v, and n coordinates to determine the direction of the smoothing.

Smooth factor per step

Sets an amount of smoothing.

Number of smooth steps

Specifies the number of steps to iterate the smoothing factor through.

Note

• Many steps and small factor are preferable to setting the factor above 1.
• Setting the factor to 1 means the original object point locations are ignored, the new locations then are the average of the neighboring points.
