Fill a hole in a T-Spline body

Learn how to use the Fill Hole tool to create faces that close an opening or patch a T-Spline body in Fusion.

1. In the Design workspace, Form contextual environment, select Modify > Fill Hole .
2. Select one edge of the hole you want to fill.
3. Select a Fill Hole Mode:
   • Reduced Star Creates faces using the minimum number of star points.
   • Fill Star Fills the hole with a single face. This creates star points at each vertex.
   • Collapse Fills the hole by collapsing all vertices to a central point.
4. Optionally, check Keep Creases to maintain creased edges when filling the hole.
5. Click OK.

Tips

• It is generally good practice to use as few star points as possible. You should only use the Fill Star mode if minimal distortion of the shape is required.
• Use Reduced Star to maintain symmetry.
