Fill holes in a polygon mesh

The Fill Hole feature lets you automatically create a three or more sided face to fill an open area on a polygon mesh. The open area must be surrounded by closed border edges.

The Fill Hole feature is useful when importing polygonal models from other software applications where the meshes have holes, or to correct and rebuild models that imported with the polygon mesh corrupted in some fashion.

To fill holes in polygons

1. Select the border edge you want to fill.
   
2. Select Mesh > Fill Hole.
   

This action creates a node called polyCloseBorder.
