Fill Hole

Fills holes in subdivision geometry by adding one or more faces. Use this tool to fill a hole or close an opening in a subdivision object.

Access the tool from the Subdivision Palette:

Subdiv Fill Hole settings

Multiple Faces - Fills holes with multiple faces using a best fit algorithm, which outputs the best position and orientation for the faces.

Note: You can use the Subdiv Cut tool tool to improve the quality of the resulting fill geometry.
Single - Fills holes using a single face.

Fill holes workflows

You can use the Subdiv Fill Hole tool to fill holes between subdivision edges or close openings in subdivision bodies.

Shift-select the tool to open the control window.
In the control window, select whether to fill the hole with multiple faces or a single face.
Click an inner boundary edge of the hole or box select the area.

The hole in the subdivision object is filled with new geometry.

Tip: To improve the topology of the fill geometry, use the Subdiv Cut tool to rebuild and add edges.
