Mesh Tools-Fill Hole tool

In the Input Parameters section of the dialog, enter a set of connected nodes that define a boundary to fill with triangles.

Note: Many of the mesh tools involve selecting or manipulating nodes. Ensure that the nodes in the part are visible and selectable by activating the required layers in the Layers pane.
Note: The Fill Hole command works on triangular elements, and cannot be used on tetrahedral meshes.
