The RebuildEdges command restores original 3-D surface edges that have been forced away from the surface through editing.

This command is useful for restoring original 3-D edges of surfaces after exploding a polysurface into separate surfaces.

**Steps**

* Select an object.

**Example**

1. Draw two planes several units apart.
2. Force Rhino to join the surfaces with the JoinEdge command.
3. Explode the object and then use the RebuildEdges command to restore the edges.
